Save yourself from problems with displaying mime-type icons in your system:
- Switch to a different system icon theme
- Delete the unwanted package:
rpm -e --nodeps adwaita-icon-theme
...or install the simulated empty package to exclude updates.
Patch package that eliminates the overlap of mime-type icons in adwaita-icon-theme
In the version adwaita-icon-theme-3.37.92 and higher, the icons of the mime types application-x-generic.png overlap the newly created mime types from the hicolor theme and puts empty icons instead of the mime icons of the application files. Only after manual intervention it becomes possible to see the real icons of
a particular mime type: rename -v \.png \.bak $(find /usr/share/icons/Adwaita/*/mimetypes/ -name 'application-x-generic.*'); gtk-update-icon-cache -f /usr/share/icons/Adwaita/
A prime example is VirtualBox and virtual machine file extensions: *.vdi, *.vbox, *.vmdk. This is just one example.
With the release of adwaita-icon-theme-3.38.0, the fault is present globally. Tested in Fedora 33 (Gnome/Mate), Solus 4.1 (Budgie/Mate/Gnome), Mageia-8 (all DE).
The latest version that works correctly - adwaita-icon-theme-3.37.2.
The adwaita-mime-patch package contains a couple of scripts for the %post and %postun events:
%post
rename -v \.png \.bak $(find /usr/share/icons/Adwaita/*/mimetypes/ -name 'application-x-generic.*'); gtk-update-icon-cache -f /usr/share/icons/Adwaita/
%postun
rename -v \.bak \.png $(find /usr/share/icons/Adwaita/*/mimetypes/ -name 'application-x-generic.*'); gtk-update-icon-cache -f /usr/share/icons/Adwaita/
After installing this patch, the display of mime-type icons works correctly. After deleting the package, everything returns to its original state. That is, to quickly roll back when the problem is resolved.
