Disable system keyboard repeat for the running window

[ReallyWeirdCat]

When a key is held, keyboard repeat on the host system is passed to the running window, which causes problems in games and audio editing programs. I'd want an option to disable this, but currently the only workaround I found is to temporarily disable keyboard repeat on the host system.
Running EndeavourOS with X11 KDE Plasma if relevant.

The kbdrate command might help.
Try something like --runfromhost 'kbdrate --rate=0'
