In openQA testing of the new mesa 22.1.0 update on Rawhide, several GNOME tests failed. One failed because the top bar was not visible after log in:
https://openqa.stg.fedoraproject.org/tests/1805240#step/_graphical_wait_login_2/9
two failed because somehow password entry at GDM failed (which is an odd failure case, not something the test system usually has problems with). Not quite sure what's causing that.
Stepping through video of the failed test and even of tests that passed, there's obvious visual glitching, things not getting fully redrawn. One instance of glitching was caught in a screenshot:
https://openqa.stg.fedoraproject.org/tests/1805240#step/_graphical_wait_login_2/7
and you can see others by stepping through the videos:

Even this passed test shows glitching in the video:

Watch from about 0:57 when log in to the updated system starts.
The VMs used in openQA are qemu VMs with virtio graphics. Full qemu command line:

System logs from one of the failures seem to show llvmpipe having some trouble:
