I have this problem with fullscreened Shatterline launched via Proton, and fullscreen Minecraft both launched on NVIDIA GPU (offload) with AMD APU as the main card. Present only on Wayland.
So if I launch some applications with my NVIDIA GPU in fullscreen mode on an external HDMI display connected to my laptop, external HDMI output will freeze, but the application will not crash and even will keep rendering on NVIDIA GPU. If I try to replug the frozen display or just disable-enable it via KDE Plasma settings, my whole graphics system will freeze, and after that I’m not even able to switch to a different TTY.
Problem started to appear after a relatively recent NVIDIA driver update.
A bit more details about my previous attempts to retest this bug.
Retest was done at the same laptop, the same OS version (snapshot) and even with the same KDE Plasma and Kwin versions. The only thing that I changed in my system is the official NVIDIA driver version (installed G05 instead of G06 [see the official NVIDIA driver repo for openSUSE Tumbleweed]).
Also this bug appeared during 5xx driver updates, but not during upgrade from 4xx to 5xx.
Here what my zypper will do if I ask him to downgrade to the G05:
root@yspace ~# LANG=C zypper install nvidia-computeG05

Just got this bug on X11.
On X11 I’m able to control the lagged external display colors via NVIDIA Xserver Settings, and just torn off-on the display in system settings in order to “fix the display”.
Also there was a system lag after turning my external display off.
Wayland? A pinned post says not everything works on wayland EGL (egl is made for apps that want and older more stable GL, not for new features).
I don’t think nVidia owes Ubuntu KDE Suse more packges (infact i wish they’d help wider platforming not favor 2 or 3, personally). You didn’t say what OS your using what version, what version of Xorg (X11 is incorrect).
“wayland” is an “X wrapper” as is gtk or kde. it is continually changing versionally - and i wouldn’t be API are stable (ie, already released features canceled in new API - which KDE and GTK continually due against all rules).
to make matteres worse, Xorg has rapidly been hacking wayland features “that can’t be removed” from X as well as GL features that cann’t be removed
this makes predicting “what one means by saying on wayland” wildly un-predictable as to determining a cause.
The problem is that no errors are logged apart from sometimes an Xid 56, “Display Engine error”, telling only what you already know, the nvidia gpu has an issue with its hdmi port.
Likely won’t help, but did you already check for a bios update?
2022-11-28 version 525.60.11
* Improved the performance of PRIME render-offloaded applications.
but wasn’t fixed with
======== Release 530 Entries ========
* Fixed a bug that prevented PRIME render offload from working for
Wayland applications when running on a system with an AMD iGPU.
Though that likely addressed a different bug.
At least the other person found a workaround by using gamescope.
