Updated to Thunderbird 91.2.0 and, ever since, screen flickers while using. This only happens in Thunderbird; it's not a monitor issue.

Not using hardware acceleration and do not have any extensions in use.

Chosen solution

Does it improve if hardware acceleration is enabled? Any difference in safe/troubleshoot mode (hold Shift when launching TB), which involves more than disabling add-ons and hardware acceleration.

Thank you - starting in safe mode did the trick.

Was hardware acceleration enabled in normal mode when it flickered? If it wasn't, and the flickering disappears in safe mode, try launching again in safe mode, 'Reset toolbars & controls', 'Make changes & restart', and see if flickering is now absent in normal mode.
