I have an issue with NVIDIA and wayland which persists since Kubuntu 22.10. It still happens in 23.10.

Normally I run Wayland with the integrated Intel GPU and everything is fine.

If I want to play a game then I run "prime-select nvidia" and reboot. However if I run "glxinfo | grep renderer" after that, the output is the Intel GPU. ("prime-select query" outputs nvidia).

If I switch to X11 then everything runs on the NVIDIA GPU which is fine. But I wanted to use Wayland with NVIDIA and thought it should work by now.

Any ideas what is going on?

I am running Kubuntu 23.10 on Wayland and Firefox (snap version) does not show a Minimize or Maximize Button anymore in the top right corner (see attached screenshot).

How can I bring these buttons back?
