Yeah help please cause this a big annoyance for me
Can you explain the problem in a bit more detail. For example, what does GTK theme change from and to?
The wallpaper, where? On the desktop? What does it change to?
This happens to me as well. Sometimes my wallpaper changes to an EOS wallpaper, sometimes there’s no wallpaper, just a black screen. All else is present (i.e) plasma panel etc…
When that occurs, I just reapply my wallpaper, (minor annoyance)
