Created attachment 165619 [details] configurationg change script SUMMARY I have the following setup: 2 screens, fractional scaling 150%, the bottom one has adaptive sync (see the screen configuration screenshot) I use zsh aliases to change between day/night mode STEPS TO REPRODUCE 1. Configure an adaptive sync screen to have "adaptive sync: always" 2. Open a terminal and move it and the mouse cursor to the adaptive sync screen 3. Run the attached script which: - Changes the wallpaper - Changes the screen backlight level - Changes the color temperature - Changes the cursor theme & color scheme OBSERVED RESULT The Adaptive Sync screen freezes EXPECTED RESULT The screen should not freeze SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.93.0 KDE Frameworks Version: 5.249.0 Qt Version: 6.7.0 Kernel Version: 6.7.3-zen1-2-zen (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 5800H with Radeon Graphics Memory: 23.1 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 3050 Ti Laptop GPU/PCIe/SSE2 ADDITIONAL INFORMATION Setting 'adaptive sync' to 'Never' or running the actions sequentially works as a workaround ADDITIONAL ENVVARS # workaround for nvidia+amd hybrid setup lags export OGL_DEDICATED_HW_STATE_PER_CONTEXT=ENABLE_ROBUST # workaround for cursor not respecting night color export KWIN_FORCE_SW_CURSOR=1

It requires multiple runs of the script to reproduce the issue
It should be fixed with https://invent.kde.org/plasma/kwin/-/merge_requests/5038. If you can still reproduce it on git master or in 6.0 anyways, just reopen this
Can still reproduce on git master (6.0.0_r26100.g7644499e20) Now the log right after the freeze is the following : Feb 09 23:26:28 laptop kwin_wayland[248173]: kwin_wayland_drm: Pageflip timed out! This is a kernel bug Feb 09 23:26:28 laptop kwin_wayland[248173]: kwin_wayland_drm: atomic commit failed: Device or resource busy Feb 09 23:26:28 laptop kwin_wayland[248173]: kwin_wayland_drm: atomic commit failed: Device or resource busy And it keeps showing `kwin_wayland_drm: atomic commit failed: Device or resource busy` for each subsequent screen update in the system log
Edit: it's not git master, the latest log is with `Plasma/6.0` kwin branch
hmm, the newly implemented page flip timeout fallback doesn't recover the session, but it at least tells you about the actual problem now: "This is a kernel bug". "atomic commit failed: Device or resource busy" also confirms that it's not just KWin misreporting anything, but the kernel is convinced that there's still a frame that needs to be presented first. Please report this to https://gitlab.freedesktop.org/drm/amd/-/issues, and attach the same snippet from the log + the output of dmesg after triggering the problem there.
It's on NVIDIA, not AMD (the integrated is disabled in BIOS) Probably it's https://forums.developer.nvidia.com/t/545-29-06-18-1-flip-event-timeout-error-on-startup-shutdown-and-sometimes-suspend-wayland-unusable/274788
Interesting that it allows disabling the integrated gpu entirely. Does it have a mux switch for the internal display?
Yes, it has a mux switch
