Missing half of top menu bar

[Procrastinus]

OCLP is running Big Sur on my iMac 12.2. The complete left side fo the top menu bar has disappeared, so I have lost the Apple logo and other icons. The right side still is present but now transparent. Any ideas on how to restore it as I can only shut down via the power switch.

Have you tried changing display resolutions in settings to see if maybe a change to something else then back again gets things back to normal?

Thank you - and yes

Gave up! Reinstall seemd to be the best and quickest option!
