I am using Ubuntu 23.10.1 with KDE Plasma desktop environment. Since recently I've been experiencing the following problem with Firfox document viewer: after a period of inactivity, PDFs become unreadable, and seem to cumulate everything that was displayed on screen (see screenshot). Ctrl + F5 does not help, and neither does closing the window and opening a new one with a link to the file. KDE Document Viewer displays the same file correctly.

Does it still happen with hardware acceleration disabled?

Does it still happen in a new profile? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile. Make sure you stay signed out of your sync account when testing.

Does it still happen with the flatpak package?
