[SOLVED] Yellow glow around letters

For some time I noticed that I have a yellow shadow on about letters in many programs. I'm sending a screenshot ↓ What is it caused by?

This is caused by "LCD sub-pixel anti-aliasing". It's supposed to make text sharper by using the red-green-blue sub-pixels of an LCD display.

Now I noticed that the problem is with Firefox, Chromium, Thunderbird
I have no such problem at Dolphin ↓

My shot in the dark here would be the difference has something to do with the way GTK/Gnome vs. QT/KDE is handling your font subpixel/lcd/anti-aliasing/rendering. If all of your KDE apps seem fine, then it's something with your GTK setup. I'm guessing you are using primarily using KDE if you have Dolphin running. One other outlier possibility would be the differences between how KDE/GTK is handling font DPI.

Re: [SOLVED] Yellow glow around letters

For gtk you may have to set it in your settings.ini or xsettings. Maybe there is a way to do that in the KDE settings, but I wouldn't know.

https://wiki.archlinux.org/index.php/GTK#Examples
https://wiki.archlinux.org/index.php/Xsettingsd

With wayland, gtk uses either a xdg settings-portal, a gnome-settings-daemon plugin or values from gsettings. The gsettings keys are here: https://gitlab.gnome.org/GNOME/gtk/-/bl … nd.c#L1675

Re: [SOLVED] Yellow glow around letters

You're right I'm using KDE (I'd love to switch to XFCE but no XFCE can't handle my setup).

I am having problems with applications built on GTK.

https://wiki.archlinux.org/index.php/Xsettingsd

I did. I don't see any changes

https://wiki.archlinux.org/index.php/GTK#Examples

I have it at home ↓

cat ~/.config/gtk-3.0/settings.ini

gtk-button-images=true
gtk-cursor-theme-name=breeze_cursors
