I've found that other people with RX 5600 XT had problems with this version of mesa.
https://bugs.archlinux.org/task/70554 https://gitlab.freedesktop.org/mesa/mesa/-/issues/4691 There is a new release of mesa (21.0.3-2) that fixes the problem for those users. Hope that you upload it to focal-proposed. ** Bug watch added: gitlab.freedesktop.org/mesa/mesa/-/issues #4691 https://gitlab.freedesktop.org/mesa/mesa/-/issues/4691 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1934783 Title: Graphical glitches with Mesa 21.0.3 on AMD Radeon RX 5600 XT To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1934783/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
