I tried to start the latest CinGG Appimages in a terminal and got several libGL errors. Any suggestions to the reason and how to solve it? 1) As user: terje@localhost:~/Applications> ls -1 CinGG* CinGG-20230430-x86_64_bb12884636d31e78f606210fbe8af744.AppImage

What happened here was that the CinGG AppImages were moved from my user's ~/Applications to /root/Applications Well, confusing, but I simply moved the CinGG Appimages back to my user's ~/Applications again and they also appeared again in Gnome Favorites.
