Created attachment 166141 [details] Video of glxgears running SUMMARY I am experiencing a stutter or flicker that almost looks like it is re-showing prior frames. Experienced it in Yuzu, freetube and glxgears(when framelimited). When I tried to capture with Spectacle it didn't capture it in the recording. Attached from my phone. STEPS TO REPRODUCE 1. Run 'MANGOHUD_CONFIG="fps_limit=20" mangohud glxgears' OBSERVED RESULT flicker EXPECTED RESULT No flicker 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: 6.7.6-273-tkg-linux-tkg (64-bit) Graphics Platform: Wayland Processors: 24 × AMD Ryzen 9 5900X 12-Core Processor Memory: 62.7 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 4080/PCIe/SSE2 Product Name: X570M Pro4
This is a NVidia driver bug, see https://gitlab.freedesktop.org/xorg/xserver/-/issues/1317 for more details
(In reply to Zamundaaa from comment #1) > This is a NVidia driver bug, see > https://gitlab.freedesktop.org/xorg/xserver/-/issues/1317 for more details While I don't disagree about the Nvidia driver bug, I have been experiencing it with wayland apps as well.
While NVidia has a workaround for Wayland native apps, that workaround can introduce some glitches as well. They're of a different sort though, so this is a bit surprising. I implemented an optimization for the NVidia driver just after 5.93.0 was tagged, which might be relevant. Can you still reproduce this with 6.0.0?

Can you still reproduce this with 6.0.0? I have not been able to reproduce it in any wayland apps anymore. I am pretty sure that I was experiencing with a wayland app, but that one decided to stop doing it. All the other occurrences are Xwayland. Thank you for your time.
