--- Comment #7 from Ivo Ivanov logos128@gmail.com --- It doesn't happen on all games. It seems to be mostly present on games that include hotfix messages (w/o picture) in their update history. In some games I have to scroll-down the update history and go with the mouse over such message to reveal the problem. Although there are games with hotfix messages, that still render the game info correctly.
Games that show the problem are: Aerofly FS2, Assetto Corsa Competizione, Automobilista 2, Elite Dangerous, X-Plane 12, etc.
Games that display their pages correctly are: BeamNG.drive, Forza Horizon 5, RaceRoom Racing Experience, etc.
The bug can only be observed with GPU accelerated rendering enabled in Steam. I only have racing and flight games in my Steam library, so can't give other examples. The store and other parts of Steam render correctly though.
Also tested with 550.78 release driver and 550.40.61 vulkan dev beta driver. The bug is still present with these drivers (on my side).
