If you have double screen, you try to pass pitool to the secondary screen while it is in use at least, the app goes crazy and is reduced to a very small square that can not be fixed unless you close it and open it again.
I have 2 screens connected to the pc the primary 4k and the secondary 1080p.
PS: It is not a serious failure but facing the future with little priority would be fine to be fixed.
Thank you
A greeting.
