Okay so, by putting TearFree in /etc/X11 (I added a file, 20-radeon.conf), the Z shaped tearing disappears from GNOME-MPV (Thanks!) But...
... the flicker (the imgur video I sent you) is still there, so I don't think that that flicker is caused by the radeon drivers, especially because it doesn't occur with the old Yaru theme. I think it would occur regardless of the theme if it was the drivers' fault. It doesn't occur on Arch either, and Arch uses these same radeon drivers - I tried different variations of these drivers on Arch to see if I could cause the flicker to show up, but I couldn't. I also tried changing the shell theme in Ubuntu from Yaru to Adwaita and that had no effect. Using various video output options in MPV yields the same results, bug's still there. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1845102 Title: [radeon] Video tearing in Gnome-MPV/Celluloid in Xorg sessions (but not Wayland) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-mpv/+bug/1845102/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
