[BUG] Input of certain letters not possible (Mobian@Pinephone)

[nuehm-arno]

Description

It is currently not possible to enter the letters "z", "o", "x", "é", "ö", "ü" (=Pos1-key), "ô", "W" into the input field in Axolotl chats using the Pinephone keyboard squeekboard. It seems to be an Electron/Axolotl thing, because starting Electron itself via terminal (~/.config/textsecure.nanuc/electron/vendor/electron-linux-arm64/electron https://...) is not producing this bug and entering the specific letters is possible.

Steps to Reproduce

1. Start Axolotl
2. Open chat
3. Try to write one of the above mentioned letters
4. Nothing is shown in the input field

Expected behavior:
Every letter to be shown.

Actual behavior:
Some letters are not shown.

Versions

v1.0.7

Sounds a lot like the issues I have had when I last tried Chromium with the Ozone Wayland backend, which is being used here. Chromium might be the culprit here – or Squeekboard.

[nuehm-arno]

Thank you very much. Starting Electron 15.3.0 without the Ozone Wayland backend let's us write the letters again.

So the question at the moment is: Nicer look and faster haptic or entering all letters.

I am also having this issue, but with different letters.

Description
Portrait mode "e" "f" "h" "i" "r" "u" "y" "z" do not show. All uppercase letters work.
Landscape mode "f" "u" do not show up. All uppercase letters work.

@mikeshenson Thanks for confirming.

Since the Electron team seems to have high requirements for their bug/issue solving (I was asked to file in some testcases with code etc.), I propose to not use the Ozone platform on the Pinephone and switch back to the blurry times - which is sad though. But I will keep an eye on Electron with every new release to see, if there is improvement. What do you think @nanu-c ?

[nanu-c]

But yes i would revert the previous version.
I hink we can do a small app as they want because it's just a <textarea \> or <input type="text" />that has this problems. And if not it's a problem with astilectron.

[kmsgli]

How can i fix this issue what is the proper way to run electron without ozone?

[nuehm-arno]

That feature is hardcoded in main.go - I will provide a Mobian specific patched version today, where the Ozone platform is disabled. So everyone can choose.

[nuehm-arno]

Here is v1.0.8-3 for Mobian user with Ozone deactivated - all letters except ü and V are back. The screen is blurry and Axolotl is laggy as in the good old times.

[mikeshenson]

I would like to add more testing data. I am still running the Axolotl 1.0.8.

I have a custom squeekboard layout that I added memory preset to (i.e. "Heading Home" or my email address)
The memory presets also have issues with the same missing letters.

All keys work properly with an external keyboard plugged into the Pine64 docking bar.

I found a work around to show all letters:
Open gedit and type out a message >> select all >> copy >> open Axolotl and paste text in a message.

So it appears, that squeekboard has been tracking this "situation" since ages:
https://gitlab.gnome.org/World/Phosh/squeekboard/-/issues/244

And it looks like ultimately the chromium / electron patch should probably be upstreamed by somebody,
who can confidently argue about correctness in ui/events/ozone/layout/xkb/xkb_keyboard_layout_engine.cc.

In the meantime we have some temporary workarounds:

1, Not using squeekboard, but an actual keyboard because squeekboard is not a keyboard but an input method.
A good candidate is the PP keyboard for example, but other HW or SW keyboards could work.

2, Copy paste from scratchpad like mikeshenson suggested.

3, Create custom squeekboard layouts where you have all your previously missing letters on some auxilary extra layer,
depending on what your original layout was. Or just try out some other already existing layouts.
On my private layout I haven't even noticed this issue for quite a while.

4, Axolotl packagers could try to apply and ship the chromium / electron patch.
The practice of "silently" downloading some binaries from github is not really a good security practice anyway,
I think most of the users would prefer to get electron from the same trusted source,
where Axolotl also came from.

[nuehm-arno]

Thanks for the research, @Ferenc- .

I agree, that the silent binary download is not the best practice. I haven't tried to build Electron myself, but since the patch for squeekboard usage seems really necessary, one should look into that. Shipping the patched Electron binary inside the Mobian/Debian-arm64 package could be a good solution.

I'll have a try soonish and keep you posted...
