So I tried running Anki in KDE Plasma 6 and the fonts are blurry. I have a 125% scaling in KDE and Anki. Even with 100% scaling in Anki the fonts are blurry. In legacy X11 Applications I have the set the applications to apply scaling themselves
I see the following lines in command line:
Qt warning: The cached device pixel ratio value was stale on window expose. Please file a QTBUG which explains how to reproduce.
Is there a way to fix it?
Does this help? Wayland - Anki Manual
Wayland support is not ready
See Wayland issues · Issue #1767 · ankitects/anki · GitHub for discussion and bug reports
i will just run in X11 mode with QT_QPA_PLATFORM=xcb variable until the bug is fixed
Did the variable QT_SCALE_FACTOR_ROUNDING_POLICY=RoundPreferFloor did not work? or is it another problem with fractional scaling?
I tried it now and it works 
Hi. I am also getting the blurry fonts in wayland (hyprland)
export QT_QPA_PLATFORM=wayland
export ANKI_WAYLAND=1
export QT_SCALE_FACTOR_ROUNDING_POLICY=RoundPreferFloor
in ~/.bashrc
one of those fixed the error message OP was getting but the weird blurry font persists
update : the conjunction of the following 2 lines in hyprland.conf fixes the issue…
monitor=,highres,auto,$INTEGERand
QT_SCALE_FACTOR,$INTEGERwhere INTEGER is any positive integer.
the problem with this solution is that everything else scales with the monitor setting, and 1 is too small while 2 is too big. The rounding policy environment variable doesn’t seem to work
