Package: mutter Version: 3.34.4-1 Severity: important Dear Maintainer,
When upgrading mutter from 3.34.3-1 to 3.34.4-1 (testing), my second screen (eDP / 3440x1440) is completely white, the second one show glitches and freezes during a few tens sec. probably while trying to sync the other one before aborting. Downgrading to 3.34.3-1 + restart gdm3 fixes the issue.
