Non-English keyboards sometimes stop emitting characters

[Ohad Lutzky]

I have English, Hebrew, and Japanese (mozc) configured as my keyboard layouts. This usually works fine. However, frequently (maybe once an hour), only the English layout will emit any characters in specific apps - namely google-chrome and obsidian (both chromium-based 🤔). This is a regression since 24.04 (23.10 didn't have this).

Removing Japanese (mozc) doesn't help, this issue still reproduces.

1. I switched my keyboard to Hebrew using the keyboard shortcut
2. The indicator did indeed show Hebrew
3. I focused Google Chrome's URL bar and pushed letter keys on my keyboard

What I expected: Letters show up the URL bar
What happened: Nothing

Hint: Opening a Gnome app, such as hitting Alt+F2 to run `ubuntu-bug`, or running `gnome-text-editor`, seems to temporarily fix this issue.

I'm not sure which package causes this. However, journalctl does have these logs show up at roughly the same time:

That flood of log messages is usually harmless, and is tracked in bug 1857392.

[Ohad Lutzky (lutzky)]

This is reproducing right now. Interestingly, when using the Hebrew keyboard layout, typing non-Hebrew characters which are available in this layout work just fine: numbers, punctuation, capital letters in English when holding Shift. So it's something about Hebrew letters being typed.

Japanese, is also broken at the same time - it opens the little mozc choices menu based on what I'm typing, but none of this makes it to the browser window.

Opening a terminal window to try and identify log messages seems to have undone it. Nothing relevant identified other than the "Overwriting existing binding" messages I've pasted above.
