Nvidia Delayed Frames Bug
Since quite some time (over a year) I have massive problems with native Nvidia drivers for my 1650 super on OpenSuse Tumbleweed.
Currently I run Gnome on Wayland.
Symptom is in many applications graphics do not work properly:
- Chrome (and many other apps, like yast or my own chordsplay tk app) has delayed frames: On user action the gui is not updated or not fully updated. A mouse click somewhere in the window can cause a redraw most of the time.
- VLC videos start stuttering and displaying frames in the wrong sequence. Can be helped by selecting Tools/Settings/Video/Output: XVideooutput (XCB)
Record configuration / status

Xorg works
- select "Gnome on Xorg" during session login
job4:~ > env | egrep 'XDG_SESSION|XDG_CURRENT' XDG_SESSION_DESKTOP=gnome-xorg XDG_SESSION_TYPE=x11 XDG_CURRENT_DESKTOP=GNOME
It is important to not have environment variable QT_QPA_PLATFORM=wayland set.
It could be set in many places (service files, user profiles, ...)
/etc/profile /ect/profile.d/ /etc/bashrc.* ~/.bashrc ~/.profile ~/.config/environment.d/ /etc/systemd/user.conf /etc/systemd/system/user*/ /etc/systemd/user.conf /usr/lib/systemd/ /etc/systemd/
After removing the variable from .bashrc I had to reboot to get rid of it. Logout/login was not enough.
Check with
systemctl --user show-environment | grep QT_QPA_PLATFORM
