[Desktop-packages] [Bug 1896167] Re: Heavy screen tearing in Wayland sessions on Raspberry Pi 4-B (using the FKMS driver)

Seems to depend on clock frequency, just like I see with Intel graphics. If you spin the CPU at 100% like: while true; do true; done then the clock frequencies increase and desktop frame rates become very smooth. But that's also when the tearing starts. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1896167 Title: Heavy screen tearing in Wayland sessions on Raspberry Pi 4-B (using the FKMS driver) Status in linux-raspi package in Ubuntu: Triaged Status in mutter package in Ubuntu: Triaged Bug description: Heavy screen tearing in Wayland sessions on Raspberry Pi 4-B when using the FMKS driver, meaning you have: dtoverlay=vc4-fkms-v3d To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1896167/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp

The tearing still happens in hirsute, but only when you can convince the system to render at 60Hz. Most of the time it's stuttering (30Hz) and not tearing. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1896167 Title: Heavy screen tearing in Wayland sessions on Raspberry Pi 4-B (using the FKMS driver) Status in linux-raspi package in Ubuntu: Triaged Status in mutter package in Ubuntu: Triaged Bug description: Heavy screen tearing in Wayland sessions on Raspberry Pi 4-B when using the FMKS driver, meaning you have: dtoverlay=vc4-fkms-v3d To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1896167/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
