application crashes after rectangle selection. in gdb, the problematic line is at line 963 : https://git.xfce.org/apps/xfce4-screenshooter/tree/lib/screenshooter-capture.c#n963 size_window seems invalid. removing this line solve the problem
I get no crashes here with gtk 3.24.10 and glib 2.60.6, which versions are you using? And which screenshooter version? > size_window seems invalid. > removing this line solve the problem And may create a memory leak, not a big deal now that screenshooter doesn't allow retries or is not a daemon, yet a bad practice to remove clean-up code without understanding what's wrong.
