[Solved] Fonts in Anki looks pixelated ( not sharp )

phoenix324 · 2023-09-02 18:08:34

I asked on Anki_Forum and they said

Given that it happens with both system and bundled Qt libraries, I’m guessing it’s some font-related issue. Your distro’s forums may have some ideas.

also i have

noto-fonts-cjk

.

Other than this i haven't done any explicit font configuration.

Make that "1", still blurry?

Does your anki use xwayland?

I switched scaling to 1, and it looking good now. But i need 1.25 scaling. 1 is too small , 2 is too big. 1.25 is perfect.

No it is not using xwayland by default . i have currently these variables exported in environment ->

In .bashrc

export QT_QPA_PLATFORM=wayland
export ANKI_WAYLAND=1

In hyprland.conf

env = XDG_CURRENT_DESKTOP,Hyprland
env = XDG_SESSION_TYPE,wayland
env = XDG_SESSION_DESKTOP,Hyprland
env = GDK_BACKEND,wayland
env = QT_QPA_PLATFORM,wayland
env = QT_QPA_PLATFORMTHEME,qt5ct
env = QT_WAYLAND_DISABLE_WINDOWDECORATION,1
env = QT_AUTO_SCREEN_SCALE_FACTOR,1
env = XDG_PICTURES_DIR,$HOME/Pictures

Also this is applied to force-zero-scaling for xwayland ->

# unscale XWayland
xwayland {
    force_zero_scaling = true
  }

-------------------------------------------------------------------------

Observations ->

If i force anki to use xwayland by setting

exort QT_QPA_PLATFORM='xcb'

, anki runs under xwayland and perfectly renders fonts.

The problem is , i don't want all apps to run under xwayland by setting QT_QPA_PLATFORM='xcb', if the only solution is to run anki under xwayland , is there a way to specifically force only anki to use xwayland.

I tried setting export ANKI_WAYLAND=0, but it has no effect , only QT_QPA_PLATFORM='xcb' affects wether it will run under wayland or xwayland. ( i will ask on anki forum about this ,just in case ).

You could shadow /usr/bin/anki w/ /usr/local/bin/anki

#!/bin/sh
exort QT_QPA_PLATFORM='xcb'
exec /usr/bin/anki "$@"

But it would seem a bit weird that Anki is the only Qt/wayland client that ends up w/ supersampled text scaling.
o/c there's not gonna be a problem if you unscale Xwayland (where otherwise the blur would be systematic, what I initially suspected to be the reason)

phoenix324 · 2023-09-03 07:53:51

Sorry, i didn't understand what `o/c` and `/w` meant. `/w` most probably would be 'with'.

For now , i am going with

alias anki='QT_QPA_PLATFORM=xcb anki

I will leave this Post opened for some time as i have asked on anki-forum to, after i received you reply wether it is a known bug or just specific to me. Thanks for the help.

phoenix324 · 2023-09-03 08:33:15

Now i realise you solution of shadowing anki is way better , Thanks.
