SUMMARY When playing a video in VLC with the output set to automatic (in Wayland), it jumps backwards two or three times a seconds for just an instant. This results in a flickering effect. STEPS TO REPRODUCE 1. Use Wayland. 2. Have VLC media player. 3. Play a video with VLC. OBSERVED RESULT The video stammers. EXPECTED RESULT The video plays continuously. SOFTWARE/OS VERSIONS Windows: X macOS: X Linux/KDE Plasma: Fedora 40 x64 (available in About System) KDE Plasma Version: 6.0.5 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.1 ADDITIONAL INFORMATION I am using NVidia graphics with the proprietary drivers.
Hello, thank you for report. Please try to disable or remove your proprietary driver's. If it will work as expected, it will be upstream bug. Thank you Daniel
I uninstalled akmod-nvidia and rebooted. The problem persists. However, I still have VRAM reports? That has never happened before when the drivers were not working.
Is there any reason to suspect this is anything other than a VLC issue?
I honestly don’t know. I have no idea how Wayland works and I’m not sure what level it is at, I just know X support is dying in Fedora spin KDE to the point where it is now far worse than Wayland, and I need this to work. Everyone involved can say “wrong department” and I won’t know if they’re wrong, but I won’t know who to talk to.
Talked with a KWin developer, and apparently this should be fixed with Explicit Sync in Plasma 6.1, in conjunction with the version 555 or later of the proprietary NVIDIA driver.
All right, thank you. I just got the 6.1 update working today, apparently there was a conflict with some X 11 packages. Nice to know this is fixed at the same time X 11 is officially dead for me.
