Font not rendering #3

gnujeremie · 2015-12-23T08:36:43Z

I have a problem with the font not rendering correctly. I don't know if it's an electron or an nyaovim problem (or a 'my bad' problem :-D).

I removed my init.vim (neovim's vimrc), but the issue is still there.
I don't know if it's related, but the terminal displays this line a lot :

[48303:1223/093014:ERROR:gles2_cmd_decoder.cc(7333)] [.Offscreen-MainThread-0x7fecb3451ed0]GL ERROR :GL_INVALID_OPERATION : glUseProgram: program not linked

Under Mac OSX 10.11.1, and the latest version of nyavim installed with npm.

The text was updated successfully, but these errors were encountered:

rhysd · 2015-12-23T09:14:19Z

Thank for your report.

Hmm...
It seems a bug of Chromium on rendering GL enhanced canvas. I'm not familiar with Chromium. (The bug may be Electron specific.)
Anyway, I want to confirm your Electron version.

1. Start NyaoVim in debug mode

$ NODE_ENV=debug nyaovim

1. Show versions in console on DevTools

console.log(process.versions)

Note: I'm also using OS X 10.11.1 and tried latest nyaovim package but it worked.

gnujeremie · 2015-12-23T09:18:48Z

You're welcome :)
Here's the result of

console.log(process.versions)

ares: "1.10.1-DEV"
atom-shell: "0.36.1"
chrome: "47.0.2526.73"
electron: "0.36.1"
http_parser: "2.6.0"

node: "5.1.1"
openssl: "1.0.2e"
uv: "1.7.5"
v8: "4.7.80.23"
zlib: "1.2.8"

rhysd · 2015-12-23T09:27:34Z

The output looks the same as mine.
Is there any other error output in console?

gnujeremie · 2015-12-23T09:38:41Z

No, it's seems to be okay, but i'll try to dig deeper (I'm currently at work).

I have powerline installed for my terminal and my vim statusbar. I thought it could be the problem, but as I told you, even when I remove all my vim/neovim config, the font still does not render.

rhysd · 2015-12-23T09:44:29Z

Thank you for your analysis. Very helpful :)

I want to reproduce this because it is hard to fix a bug without reproducing. If you can, could you show me your init.vim? (Of course after your work ;) )

gnujeremie · 2015-12-23T10:00:08Z

You're welcome ^^

You can find my full .vim here : https://github.com/gnujeremie/dotvim (I symlink to .config/nvim and init.vim after).

I just have these lines specifically on my work station at the end of the .vimrc

" Powerline
python from powerline.vim import setup as powerline_setup
python powerline_setup()
python del powerline_setup

rhysd · 2015-12-24T16:40:22Z

Hi @gnujeremie,

Sorry for late response.

I tried your config and somehow I could start your nvim (Note that this plugin seems to have been removed.)
Although I don't install powerline yet, at least all except for it is working well.

And I have one question.
Do you use 'patched' font for powerline? Powerline requires a patched font for fancy line, I think.

If you're using such a font, could you set other font to ~/.config/nyaovim/nyaovimrc.html as below?

    <neovim-editor id="nyaovim-editor" argv$="[[argv]]" font="Courier,monospace" ></neovim-editor>

Pelase note that Courier can be other font. Please try not-patched font.

gnujeremie · 2015-12-27T16:13:26Z

Hi,
Sorry for the delay (christmas...).
I do use patched font for powerline, I will try tomorrow to disable it and I'll let you know :)

Thanks.

rhysd · 2015-12-27T16:18:24Z

Hi,

No problem. I'm not in a hurry.
Thank you for your cooperation!

gnujeremie · 2015-12-28T07:55:43Z

Ok so I changed the line as you said, the problem is still there.

rhysd · 2015-12-28T16:14:32Z

Thank you for your check.

Hmm... then I think this is a bug of Chromium (or Electron) side...

Finally could you try disabling WebGL by modifying NyaoVim/main/main.js as below in your node_modules?

--- old.js  2015-12-29 01:11:18.000000000 +0900
+++ main.js 2015-12-29 01:11:38.000000000 +0900
@@ -52,6 +52,9 @@
         width: 800,
         height: 600,
         useContentSize: true,
+        webPreferences: {
+            webgl: false
+        }
     });
     win.once('closed', function () {
         win = null;

It should disable GL in canvas.

gnujeremie · 2015-12-29T07:40:00Z

Still no differences.
Do you think I should open a bug on Electron ?

rhysd · 2015-12-29T19:00:12Z

Thank you for your check.
It must be a bug of Electron or Chromium, I think. But I don't know which the bug is derived from... 😕

Do you think I should open a bug on Electron ?

It's very helpful for me. If you do that, could you please let me know the issue URL?

rhysd · 2015-12-30T13:21:08Z

I posted a question in Atom forum.

https://discuss.atom.io/t/gl-error-in-canvas/24058

gnujeremie · 2015-12-30T13:35:47Z

Ok thanks :)

Setting Courier as default font doesn't help, nor does adding the webgl: false in main.js (assuming that worked — is there any way to check that from within the debugger console?

adelarsq · 2016-01-05T01:14:39Z

Same issue for me on OS X El Capitan. Many lines like this are shown:

rhysd · 2016-01-07T01:42:04Z

@doenietzomoeilijk @adelarsq

Thank you for report.

Hmm... no one seems not to know resolution of this problem in forum and Google Search also could not help (Only old bug report was found).
I think I should open an issue in atom/electron repository (probably today).

adelarsq · 2016-01-07T01:59:02Z

It's a Chromium bug. On this old page there are a similar bug (GL ERROR :GL_INVALID_OPERATION : glUseProgram: program not linked).

On my Windows 7 I did notice the same problem 😕
[UPDATE] On Windows works fine now, maybe something wrong with remote connections, I don't know.

marcj · 2016-02-16T12:24:39Z

We are having also this issue with our app using https://github.com/atom/electron and font rendering in canvas elements at OSX, so I guess it's a bug with their chromium version. I couldn't find yet an issue reported there about this font render error, but I don't think this is directly related to NyaoVim.

rhysd · 2016-02-24T11:00:12Z

@marcj

Thanks. Forum also seems not able to help this issue. I'll report this to Electron repository. Could you tell me what your app's Electron version is?

As @marcj said, this may depend on Chromium version. I want to confirm the latest Electron (0.37.8) causes this error yet.
Could anyone confirm this now?

gnujeremie · 2016-02-24T11:06:42Z

I updated nyaovim (v 0.0.17), electron is version 0.36.8, the issue is still here.

rhysd · 2016-02-24T11:36:44Z

@gnujeremie

Thank you!

- electron/electron#4594 - #3

rhysd · 2016-02-27T14:17:41Z

I added a workaround for this and bumped up version to 0.0.18, which was suggested in electron/electron#4594 .

Could you create ~/.config/nyaovim/browser-config.json as below and start NyaoVim? (Please ensure that NyaoVim version is 0.0.18.)

{
  "enable_canvas_workaround": true
}

adelarsq · 2016-02-29T12:29:54Z

Cool. I will try to use tonight and give you a feedback.

rhysd · 2016-03-01T06:28:55Z

@gnujeremie @adelarsq

Thank you for your confirmation. Then I'll revert the workaround 😭
I have no idea for this issue...

gnujeremie · 2016-03-01T08:02:21Z

Don't give up, sooner or later we'll find a fix :)

adelarsq · 2016-03-01T13:04:41Z

Maybe that webgl isn't enabled on the chrome that comes with nyaovim. Also we can try others options for the --use-gl flag. The flag used before (egl) still was using opengl, that is why the problem remains.

a3li · 2016-03-16T16:15:36Z

Another custom Electron app user here:
We had the same issue, we went back to electron 0.35.5 which did not suffer from it; I updated to 0.37.2 today and that seems to work as well. Maybe up/downgrading electron (aka avoid 0.36.*) can fix that for you as well.

ohle · 2016-03-23T22:01:58Z

I tried this today and can confirm that 0.35.6 solves this problem for me. Unfortunately, 0.37.2 doesn't. Also, I had to comment out the (app.dock as any).setIcon line from main.ts for the old version - no idea what else would be affected.

adelarsq · 2016-03-23T23:25:22Z

The problem may be related to this issue.

adelarsq · 2016-04-07T18:15:28Z

@ohle with 0.37.4 did work?

GnorTech · 2016-04-14T04:49:49Z

Latest NW.js 0.14.0 fixed the same issue. NyaoVim could consider migration.

rhysd · 2016-04-14T05:02:59Z

@GnorTech

That's good news. Thank you. Do you know which Chromium version NW.js 0.14.0 is based on?

GnorTech · 2016-04-14T05:20:39Z

@rhysd latest Chromium stable 50.0.2661.75 . The same issue reported is nwjs/nw.js#4618

rhysd · 2016-04-14T05:57:11Z

@GnorTech Thank you. I confirmed that Electron v0.37.5 is based on Chromium 49.0.2623.75. So I'll ping to this issue when Electron is based on Chromium 50.

p0009231 · 2016-04-14T09:34:21Z

Probably related? Setting OS language to English solved that problem for me.

gnujeremie · 2016-04-25T15:09:30Z

Same as @p0009231 , setting the language to English fixed the problem.

kuglee · 2016-05-04T10:18:41Z

Nice find @p0009231. If opening from command line one can always set LANG="en_EN.UTF-8" then open nyaovim. This way the OS language doesn't have to be changed.

adelarsq · 2016-05-15T22:43:28Z

@rhysd What about update Electron for the latest version?

rhysd · 2016-05-16T09:16:59Z

Yes, latest Electron (v1.1.0) seems to use Chrome 50 🎉

I'll update tonight.

rhysd · 2016-05-16T15:38:25Z

I updated Electron version in local environment and found behavior of KeyboardEvent.key seemed to be changed. (I think this is the difference of Chrome 49 and Chrome 50).

I need to update and fix neovim-component at first.

adelarsq · 2016-07-15T19:12:10Z

Hi @rhysd, any update on this issue? Actually this is the only reason because I still don't use NyaoVim, that is why I'm so obsessed about 😁

rhysd · 2016-07-17T17:55:01Z

I fixed KeyboardEvent.key issue which prevented Electron dependency updating to v1.2.7 in neovim-component package. Now neovim-component v0.6.0 is compatible with Electron v1.2.7 and I'll try to update NyaoVim's Electron dependency. Sorry for making you wait so long.

rhysd · 2016-07-18T07:38:50Z

@adelarsq I updated NyaoVim to v0.0.20 (Electron v1.2.7). Could you try it?

adelarsq · 2016-07-19T01:41:10Z

@rhysd Yeah! Nice! Did work! 🎆

And trying to install again.

rhysd · 2016-07-19T02:23:52Z

@adelarsq

Please do not use sudo for npm install. It tries to give unnecessarily strong permission to executable and causes an error. Please use $ npm install -g nyaovim for installation on OS X. I think unsafe-perm is not recommended in terms of security.

adelarsq · 2016-07-19T03:11:47Z

@rhysd Thanks. I did reinstall with npm install nyaovim.
For some reason there is no link for the app and show this messages:

You forgot adding -g 😃 . Please add -g ($ npm install -g nyaovim) for global installation. In previous error you kindly reported,

sudo is a problem causing the error, I guess.

@rhysd the command only works with sudo:

@adelarsq

Hmm... that looks a problem depending on your environment... I recommend to install Node.js via Homebrew or Node.js version manager like nvm, nodebrew, and so on.

Anyway, this issue was resolved 🎉
Thank you all who gave me information about this issue 😄

adelarsq · 2016-07-21T14:40:04Z

It's some weird problem on my OS X. But the main problem is solved. Thanks @rhysd 👏 👏
Next step will be make 145 plugins and 6K lines from macvim config compatible with neovim 😄
