A user reported (Bug report: 40655a60062a9dd4081d24396580f01c) that since tails 4.1.1 (they didn’t saw the issue on tails 3.x), when starting tor browser or thunderbird, the window displayed is white and the icons and menus only appears when hovered by the mouse and the window content is only displayed in stripes when scrolling.
It was also reported on this reddit post (with tails 4.0) : https://www.reddit.com/r/tails/comments/dnz93w/graphics_bug/
