I just upgraded from Fedora 33 to Fedora 34 and experienced serious issues making my computer usable. There is a rendering issue making the screen flicker/strange pixels patterns appearing for almost every app (including gnome terminal). Interestingly, the only app that seems unaffected is firefox. The only non-standard thing about my setup is that I have a 1400p 144hz display. My graphics card is Amd 5600xt so I do not think this is the issue. Has anyone else experienced this? I am not a sophisticated linux user, but I have been using Fedora for the last 10 years without issue, and usually upgrade when I hear about a new version.

  I read it as they are having trouble making the computer usable now.

  My mind automatically interpreted that spelling as "unstable". It turned out that "unusable" matches the context better.

    Ah yes I meant unstable I blame the flickering screen for the typo. I had to downgrade to 33 which was slightly annoying but no harm done. I guess I will skip this upgrade cycle and wait for 35

      well trust me, what you originally wrote would be a funny story. "broken computer got more usable, by installing broken software". and it would probably be funny to debug that! Ü

I have the exact same issue, still on 33. Running Ryzen 3600X and RX 480. I think it could be a kernel update, got bumped to 5.11.16 last night, don't recall any Mesa updates in the list (using update-testing repos).

  Interesting, I ended up testing an older 1080p monitor and had the same issue, so it really seems like it is either an issue with the Amd graphics card driver, or an issue with Fedora 34 in general. I am somewhat surprised since I have fairly common hardware , and not much customization. I'd highly recommend waiting to upgrade

  I've got similar hardware here - and just pulled down all my updates on the Fedora33 KDE spin. So far, both GTK and QT windows/UI are behaving fine for me... Some some relevant hardware/kernel info I yanked out of glxinfo. I've not looked for any bugreports, but I'm happy to follow one if I might be useful.
