IIRC, Palemoon is GTK2, right?
It’s not using the right theme from gtk-common-themes
snap, and it seems to be using some super old-looking theme + my Plasma’s current color scheme.
Here’s the YAML file.
I’m getting this output repeatedly:
(pale moon:11741): GdkPixbuf-WARNING **: 13:37:47.188: Cannot open pixbuf loader module file '/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache': No such file or directory
This likely means that your installation is broken.
Try running the command
gdk-pixbuf-query-loaders > /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache
to make things work again for the time being.
My GTK theme is currently set to Yaru
