Starting today (September 26, 2020, PST timezone), Thunderbird window, even when maximized, runs off the screen to the right, making it impossible to view and use all buttons in Message pane. I have a 1366 by 768 resolution.

The attached screenshot shows the problem, with Reply button showing on the right edge of the screen and no other button visible unless the entire window is selected and dragged to the left to bring the right edge of the windows into view.

The width of the window cannot be changed by clicking the right edge of windows and dragging to make it narrower.

See if it looks the same in safe mode, to test for a broken layout or incorrect hardware acceleration setting. Hold Shift when launching TB to run in safe mode.
