Problem with visualization (display) in Thunderbird 91. Solved by disabling hardware acceleration in Preferences
Good day. After update to Thunderbird 91, a strange issue occured. When opening e-mails a strange colour lines starting from upper left corner of the screen ("File" location) occurs. At reply/create e-mail window dark grey wide lane across the borders of TO: CC: area occurs.
Trying to solve the problem at Troubleshoot mode helps and issues disapears, but after restarts occurs againg. It looks onlu in troubleshoot mode visualization of the screens is normal and good.
I am atthaching screen shot for reference.
Than you in advance for any advices or tecnical support!
With kind regards!

Good evening! So far neither to disable all add-ons nor to reset toolbars and controls gave result, but to disable hardware acceleration in normal mode (Preferences/General/Indexing) and restart TB (in normal mode) works. Tested several times, without further issue. Thank you! I will test continuously tomorrow and will inform accordingly.

In the Troubleshoot Mode dialog, check the box to disable all add-ons and see if the issue persists. If that doesn't fix it, then choose the other option to reset toolbars and controls.
If 'reset toolbars & controls' doesn't help, disable hardware acceleration in normal mode (Preferences/General/Indexing) and restart TB (in normal mode).
