The save dialogue box on Processing IDE is capable of crashing Gnome. On KDE, the crash is caught and reported that Xwayland died, and everything works a-ok on with sway.
It’s unhappy about dbus and is fairly trivial to reproduce.
Download Processing 4.0.1 https://github.com/processing/processing4/releases/download/processing-1286-4.0.1/processing-4.0.1-linux-arm64.tgz
Run processing-4.0.1-linux-arm64/processing
Go to File > Save
After a moment you’ll be dropped back to the console.
Installing ibus and gdm and invoking gnome that was causes processing to just die without taking the entire environment down with it but I suspect that’s because things are running through X and not Wayland base on the packages that were installed along with gdm.
what if you export _JAVA_AWT_WM_NONREPARENTING=1 before starting processing?
It now says double free or corruption (!prev) after it crashes in a gnome session invoked via GDM.
If I start gnome from the shell, processing still takes the desktop environment down.
Revisited this after updating debian packages (left processing as-is), issue now appears to be resolved. I was able to save and run sketches just fine.
