I am not entirely sure there's an actual correlation here, but after I updated to Bullseye, my installation of VMWare Horizon Client started glitching out. I updated in the weekend and it was working fine on Friday, but not yesterday.
I'm not sure how to describe it exactly, but the images appear corrupted. In bigger windows, half of the window appears fine, but the other half appears like a blocky, greyish glitch. Smaller windows appear completely black (probably due to some y offset caused by the glitch, which also happens in bigger windows). Did anything regarding the graphics change between Buster and Bullseye? Did anyone else experience something similar with other applications? Thank you. -- Luiz Romário Santana Rios
