[Bug 1896167] Re: Heavy screen tearing in Wayland sessions on Raspberry Pi 4-B (using the FKMS driver)
Seems to be fixed now using full KMS. Full KMS required both: * Kernel >= 5.10.7 * Bug 1918110 to be fixed, which it now is. ** Package changed: mutter (Ubuntu) => flash-kernel (Ubuntu) ** Changed in: flash-kernel (Ubuntu) Status: Triaged => Fix Released ** Changed in: linux-raspi (Ubuntu) Status: Triaged => Fix Released ** Summary changed: - Heavy screen tearing in Wayland sessions on Raspberry Pi 4-B (using the FKMS driver) + Heavy screen tearing in Wayland sessions on Raspberry Pi 4-B -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/flash-kernel/+bug/1896167/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

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 Ubuntu Desktop Bugs, 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) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1896167/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

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 Ubuntu Desktop Bugs, 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) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1896167/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
