SUMMARY There are huge amount of kwin_wayland error messages in system journal, like "kwin_wayland[1025]: kwin_core: precision lost! floating value sent to X 72.5". This makes it difficult to see "real" error messages produced by other apps. As kwin_wayland seems to work alright, I guess either this error message can be removed, or at least it can be INFO instead of ERROR. STEPS TO REPRODUCE 1. Use wayland session. 2. Set global zoom to 250%. 3. journalctl -p3 OBSERVED RESULT lots of "kwin_core: precision lost! floating value sent to X" error messages EXPECTED RESULT no such messages SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.26.4 KDE Frameworks Version: 5.101.0 Qt Version: 5.15.7

Pushed by davidedmundson into branch 'master'. utils/xcbutils: reduce severity of "precision lost" message a debug Right now this is marked as critical, but it's not a critical error. Make it a debug to avoid spamming logs with not-very-actionable information.
