Hello,
I need to set Bounce keys option, so my keys do not get pressed twice even when I press the button once. However, this breaks hold for repeat functionality in some KDE based apps such as dolphin, settings and so on. In browsers, VSCode and other different apps it works fine. I have tried using fcitx5 as mentioned in this thread: Plasma Wayland no key repetition in console - #7 by Llama - KDE Plasma - Manjaro Linux Forum
But it does not help. I am on arch
