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).

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.

  AMD Radeon RX 5700 XT (NAVI10, DRM 3.40.0, 5.11.16-200.fc33.x86_64, LLVM 11.0.0)
  OpenGL version string: 4.6 (Compatibility Profile) Mesa 20.3.5

  Monitors: 2

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
