Mouse Cursor rendering on direct Wayland (works on XWayland)

Recently (about two weeks) my mouse cursor rendering has been distorted when using direct wayland rendering.
It renderes a s series scatterd lines over a quite large area.

The pointer still works, but you just don't know where exactly it is. The line-pattern also changes when the cursor would change (e.g. arrow to hand over a link).

The issue is only when using a GDM session with wayland. Once I start a gnome-session using xwayland it renderes normally.

The display driver is nouveau and I've experimented with installing different mouse cursor themes but that didn't fix it (so not a broken theme).

Any ideas are welcome

I am facing exactly the same problem, regardless of using X11 or Wayland. Have you managed to find a solution since then?

Are you using an nvidia graphic card with nvidia driver?

Hi Piepo,

Yes, I am using Nvidia GPU with nouveau driver. Let me tell you furthermore that I reinstalled Arch on my PC with base package and Gnome only, and start the desktop environment like this:

if [[ -z $DISPLAY && $(tty) == /dev/tty1 && $XDG_SESSION_TYPE == tty ]]; then
  MOZ_ENABLE_WAYLAND=1 QT_QPA_PLATFORM=wayland XDG_SESSION_TYPE=wayland exec dbus-run-session gnome-session
fi

Ah ok so I don't know. I had a similar problem with the mouse pointer on Friday and I was able to solve it reinstalling the proprietary nvidia driver... now I have a wrong screen resolution but the mouse is ok.

Nouveau on X11 is a known problem, https://bbs.archlinux.org/viewtopic.php … 9#p1959569
