Sorry, I dunno how to edit. ADDITIONAL INFORMATION Could not reproduce on X11. Could not reproduce on Kubuntu 21.10 live media (logged out of the default X11 session and logged in to a Wayland one - works fine) --> Kubuntu doesn't seem to apply scaling on neither X11 or Wayland sessions - wonder if scaling somehow plays a role in this issue Could reproduce on fedora 35 KDE live media (logs into Wayland by default). --> fedora auto scales to 200% I think when starting the live media Could reproduce on my openSuse Tumbleweed install by booting read-only snapshot of 18Jan (although I think that it's still on KDE 5.23.5) I wonder if this is somehow related to a recent version of Qt? On the other hand, I haven't encountered this issue on any other KDE apps, so far.

Find it here: https://photos.app.goo.gl/j1ddT769mzwGACUX8 It's a recent Mesa regression: https://gitlab.freedesktop.org/mesa/mesa/-/issues/5731 (In reply to Nate Graham from comment #3) > It's a recent Mesa regression: > https://gitlab.freedesktop.org/mesa/mesa/-/issues/5731 Thanks, following! |
