I think that’d be OK.
Though libXcursor contains a few ‘getenv’ calls, notably for
XCURSOR_PATH, which looks like it’s what we’re looking for.
I tested the attached path in a VM and it seems to fix the bug: I can
drag a window in the overview area on the right and it no longer crashes
(*and* I get a hand-shaped cursor when hovering that area :-)). And we
don’t need to modify libXcursor.
(We could do slightly better by using the absolute file name of the
actual icon theme instead of /run/current-system, but it’s complicated
because I guess it doesn’t have to be Adwaita.)
Thoughts?
