I get this bug when I try to unmask something with the maskpen holding CTRL
It looks like I have an alpha on my brush but I don't.
I tried exporting it has a ztool and re-importing it, merging it and even changing to another workstation, but nothing worked
Does someone have an idea how to debug this thing ?
