I get a warning when compiling emacs from source with the pgtk flag telling me about a known bug in my version of gtk that causes problems when opening and closing multiple emacs instances. Do you know anything about this? In particular would it be resolved by switching to the snap?
I have no idea about that compilation issue you get. Since the emacs snaps (pgtk and x) are pre built binaries, you wont get that problem. Ive been using Emacs PGTK from snaps on WSLg for a year without any issue.
You can also install pgtk emacs directly from snaps when under Ubuntu in wsl, if you prefer.
