2) It is also occurs on 19.10, I don't remember any working setup, may I try under windows 10 or could it be a hardware problem ? Extra info, displaying videos in firefox is not causing any issue, I suspect it uses different acceleration. ** Bug watch added: gitlab.freedesktop.org/xorg/driver/xf86-video-ati/-/issues #192 https://gitlab.freedesktop.org/xorg/driver/xf86-video-ati/-/issues/192 ** Changed in: linux Importance: Undecided => Unknown ** Changed in: linux Status: New => Unknown ** Changed in: linux Remote watch: None => gitlab.freedesktop.org/xorg/driver/xf86-video-ati/-/issues #192 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1900854 Title: radeon: GPU lockup when restarting a video on RV730 Status in Linux: Unknown Status in linux package in Ubuntu: Triaged Bug description: To reproduce type at a terminal or open with same file locally: mpv https://conf.tube/download/videos/ea60f030-90c1-4e8e-9782-bef14dd3b1d1-1080.mp4 Stop the video by clicking Esc. Run again and the process will be stuck on creating window frame for a while, then the video will start to show, but the video's first frame looks like blinking in this triangle mess.
