I’ve been having issue with Okular recently where PDFs have a blurry text and half cut icons. Also, all menu bar items get selected when I move my mouse over it and disappear the item completely when I hover over them again. I also tried flatpak and snaps of Okular but it did not any help.
Since I’m a new user, it seems that I cannot upload a picture or post a link. But here’s a video showing what’s wrong with Okular. https:// imgur[.]com /JqRxfUI
