caps word plus mods works only in some programms in Ubuntu

[timLoewel]

I configured home row mods and caps word.

In my Ubuntu 22.04 on a Dell Laptop, in most programs (e.g. gnome terminal, libre office, firefox) the letters, that have Mod-Tap or Layer-tap configured, are written in lower case during a caps word. In Visual Studio Code on the same system it works as expected.
Also on my Android phone it works.

e.g.
asdfGZXcVB
in Firefox.

ASDFGZXCVB
in VSCode and on my Android phone

Where asdf have mods configured, and c has a layer-tap.

Any idea?

Thanks, Tim

I tested a bit with xev.

With caps word enabled the "a" (which only works in vscode) sends this:

I see no difference.

And the output of evtest --grab when triggering capsword and then agbc.

I also see no difference 😦

[timLoewel]

I guess this is #759 (comment) the cause?

Strangely it only occurs on tap keys.

[timLoewel]

pkill ibus from here #759 (comment)
worked. So it is the same issue.

[schmjop]

@timLoewel I have the same issue as you and pkill ibus solves it for me as well.

Were you able to automate the killing of ibus?
I added the line to my ~/.profile and to my crontab with @reboot pkill ibus but after a reboot when checking if ibus is running with pgrep ibus, ibus is still running.
Thanks.
