Public bug reported: Hi,
I suspect there is an issue with radeon driver for video acceleration, I haven't investigated yet but I would investigate resources releases of VPU driver. As suggested on other (obsolete) bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1574130?comments=all I thought it was a VLC bug but actually it's also replicated using mpv: Just run mpv https://conf.tube/download/videos/ea60f030-90c1-4e8e-9782-bef14dd3b1d1-1080.mp4 It appears to work as expected Stop with Esc and run again Process will be stuck on creating window frame and then once windows is starting to show the video, desktop's frame buffer will become garbage: video's first frame looks like blicking in this triangle mess. system is still usable, audio is still playing. I logged using ssh and reported details using: ubuntu-bug linux I hope collected data is not mixed with my client's host. I can give more details or test patches.
