PS. My hunch: Most likely has something to do with the app attempting to launch after external monitor configuration changes.
Said external monitor configuration changes happen if you accidentally hit Super + P to toggle between Single monitor and Joined monitor modes and then hit it again to go back to Joined monitor upon with #GNOME summarily forgets the configuration you had before and concocts a different one on the spot (eat that, AI), forcing you to manually set up your monitors again.
@aral#Wayland or #Xorg? Wayland would be my prime suspect if you are using that?
I often have quirky screen resolution issues when swapping between monitors although not directly Gnome Settings crapping out, also I'm not on Fedora... Swapped back to X recently (after trying to run some old game) and things a tad more stable..
Right, so, if you’re using Sublime Merge on Linux (Wayland, e.g., Fedora Silverblue like me) and, after an external monitor configuration change it starts hanging your entire system (crashing and taking #GNOME with it, requiring a full restart), the workaround is to delete its session file which stores the (now illegal) last-known location of its window.
