Is anyone else having issues with display corruption on the recent betas?
I’m running Thunderbird v90.0.b1 on a freshly re-built Intel NUC Mini PC system (Intel i5-1145G7, 32Gb RAM, 500Gb SSD, Windows 10 Professional 21H1).
I also had this problem prior to the rebuild and am using the latest Intel graphics drivers (not the latest beta though), and all other hardware device drivers are right up to date.
Monitor is a Philips 242B 24" with driver and ICM profile installed. Resolution is 1920 x 1080 and scaling is set at 100%.
The preview pane works fine all of the time but on most occasions, when I open an email the top left corner of the window is corrupted. As soon as something refreshes the display, it clears the corruption and displays as normal.
Another problem I am seeing is that when I reply to an email, the message headers are bordered in a think grey box.
All other apps are working fine with no display corruption, refresh issues etc.
