Thick grey border in compose window on new install of Thunderbird

This is a new install of Thunderbird on a Windows 10 machine. When I open the compose window, there is a thick grey border around the From/To/Subject fields (left, top and right) (see screenshot).

If I enter Troubleshoot Mode and reload, then the border disappears. If I exit Troubleshoot Mode and reload, then the border reappears. There are 3 add-ons installed. If I disable these add-ons and reload, the grey border is still there. If I go into Troubleshoot Mode and select 'Permanently disable the add-ons' and 'Reset toolbars and controls', the grey border is still there. The only way to remove it is to enter Troubleshoot Mode and reload.

I have deleted the Thunderbird folder in %AppData% and reinstalled the program, but this has not helped. While I can still use the application, this border is a little ugly.

Any sugestions would be most welcome.

Thanks.

Hardware acceleration, under Preferences/General/Indexing, is disabled in safe mode. Is it enabled in normal mode? If it is disable it and restart TB.

I came to here for this exact reason, and the solution worked. Thank you so much!

I'm curious, though, why the hardware acceleration affects this border.
