vim breaks the fonts

[emmanueltouzery]

built it on fedora 20, it looks great but vim breaks it. Once I start vim, characters don't appear anymore on the screen, even after exiting screen. The cursor moves and the commands are obviously executed, but no fonts are drawn anymore.

Thank you for your report. Does the problem only appear in vim or also somewhere else? This is strange because no other Fedora 20 user reported something like that. Are you using some strange hardware/setup like a VM or something like that?

[emmanueltouzery]

You are right, it's not that simple. I think it's because I have something in my vimrc which does something to the fonts. If I start vim with:

vim -u NONE

To make it ignore my vimrc:

Then it works... It's probably because I'm using the powerline symbols (but then also my shell is using them and it still works). Trying to isolate the setting which causes the problem...

[emmanueltouzery]

OK I tracked it down to this setting in the .vimrc:

" bigger window by default
set lines=30 columns=110

Now yeah, I guess I can't get more lines and columns in an "antique" terminal. Maybe you could try to ignore such requests...

I experienced the same symptoms with Vim on BodhiLinux 3. In my case, the offending .vimrc entry turned out to be the following:

set columns=82

Anything larger than 68 triggers the issue in my environment. As a workaround and perhaps some insight into the cause, the issue is "fixed" per run of vim if I switch between fullscreen and window mode. Perhaps some reinitialization is happening on a fullscreen switch that needs to happen elsewhere as well. I hope this is helpful.

I just tested this and I can reproduce the bug. It seems that forcing the size causes this kind of behavior. A simple window resize is a workaround at the moment. Could someone test it and see if also happens upstream? https://launchpad.net/ubuntu-terminal-app

I have this problem in Arch Linux. I love Cool Retro Term by the way. 😄
