I use a paid for and licensed application in Fedora 33 with Gnome that is distributed in a .deb package. Previously, there has been no problem in using it. I did the “alien” conversion to get an rpm package and “dnf” install on Fedora 33 with Gnome as the UI and had no problems using it until a recent update. The most recent update left the icons in Gnome blank. The positions and text of the icons (there are about 5 of them) are still there but the icons are not. Since they are all variations of the parent program and are truncated versions of the parent program’s name, the text isn’t nearly enough to tell them apart. You really need the icons to tell which one you’re running.
I questioned the publisher and he acknowledged the problem and said it would be fixed in the next revision and that I should just change them manually since the icons are distributed with the program. I can’t wait until the next revision. I right click on the icons and the only apparent option would be “Details” which takes me to “Software” which says there’s no information on that application. How does one manually change the icons of an “alien” added application in Gnome? I think I found where Gnome keeps its icons in /usr/share/icons/gnome/32x32/apps and /usr/share/icons/gnome/48x48/apps. Will dropping them in the respective folders get picked up there? How so, if they’re not explicitly named? Thanks for any suggestions or tips.
