Update from GIMP 2.8 to 2.99 causes missing icons
Steps to reproduce:
- Start GIMP 2.8 (should work with any older version)
- Install and start GIMP 2.99 (I used my appimage, might work for other things as well).
- Allow upgrade
- Start GIMP again
GIMP comes up with full UI.
GIMP icons (tool bar, etc) are missing (i.e. show an empty document placeholder symbol).
The reason seems to be that during upgrade,
~/.config/GIMP/2.99/gimp.css does not seem to be created. Coying it from
gimp/etc/gimp.css or removing all of
~/.config/GIMP/2.99/ and restarting GIMP fixes the issue.
