Libadwaita apps have blurry text on KDE Plasma

Aldis Bārbelis · 2024-11-15 04:11:17

I used to use KDE Plasma around a month ago, but stopped because I wanted to try out a WM. Back then all of the libadwaita apps worked properly, and the apps worked properly in Hyprland too, but now if I go back to Plasma, the apps have very blurry text. The issue is not present while using Hyprland and only happens with libadwaita apps (GNOME Calendar, pwvucontrol)

I have uploaded pictures of what the GNOME Calendar looks like: https://imgur.com/a/gRkigi2

How could I solve this issue?

KDE on wayland? Do those clients end up runing on xwayland?

> KDE on wayland? Do those clients end up runing on xwayland?
Yes, I am using the Wayland session. I used xeyes, and the applications are running native wayland.

Here is the output of `printenv`:

I assume this is some HiDPI screen?

But looking at the screenshot: https://i.imgur.com/n3eAVjS.png
Where is that "blurry"?
Do you simply mean that the text is antialiased?

You are looking at the wrong image - the image you attached shows what it looks like on Hyprland or how it's supposed to look like. The other image of the album shows what the text looks like on KDE.

seth · 2024-11-15 15:40:24

Ah, sorry.
https://i.imgur.com/eVadwTz.png

That's some font hinting. Notice the (bold) 47.0 is the exact same rendering. Either fontconfig or the gtk config.
Do you get the same w/ a fresh user?
If not

printenv # you're looking for gtk config paths, maybe set by KDE.
# If not:
strace pwvucontrol 2>&1 | grep $HOME

there's probably some difference because KDE injects a file?

I was unable to find any special GTK configuration files, besides directly at the home folder and at ~/.config/gtk-X.0/.

Sorry, I somehow missed reading this sentence. Upon doing some research, I have come to the conclusion that HiDPI is some modern standard for Apple monitors. I have nothing like that, and I am unable to find any system settings related to HiDPI.

seth · 2024-11-15 19:58:40

No, HiDPI outputs are simply if your DPI is somewhere north of 144.

Did you try the behavior w/ a fresh user?
Probably post the strace and printenv outputs.

Aldis Bārbelis · 2024-11-16 10:08:12

The issue still occurs with a fresh user.

Geometry: 0,0,1920x1080

So probably not HiDPI

XDG_CONFIG_DIRS=/home/testuser1/.config/kdedefaults:/etc/xdg

is probably not the case in Hyprland?
Anything in /home/testuser1/.config/kdedefaults ?
Though

The issue still occurs with a fresh user.

doesn't sound like it's local.

Also do you have

GSK_RENDERER=ngl

in a Hyprland session?

In general it will be helpful to compare the KDE and Hyprland strace and printenv's and on a completely whacko theory

xrdb -q | grep -i xft

Finally, do you get this behavior in a KDE/X11 session?
And since idk what "poor" means in that context but gnome reads its config via xdg-portal… https://wiki.archlinux.org/title/XDG_De … KDE_Plasma
