Account for rare window shadow on Linux #276
Description
Describe the bug
Windows Shadows/Borders are a thing too on Linux. It seems kinda rare that's actually an issue. Might be so specific to just the finder that it's not even something I should bother with? Time will tell if users encounter this. Very low priority until an issue actually arise.
To Reproduce
an easy example is Finder in Ubuntu/GNOME . Simply use "Window selection" on it.
Expected behavior
Account for shadow when cropping, just like on Windows.
Screenshots and recordings
TODO if I can replicate it
