    Description

      When a mask is set on a widget after being moved to a different display with a different DPR then it can end up not being set correctly because it is seen as the same as the previous one, although due to the DPR change it is not the same.

      In the attached example wait a few seconds and the shapedclock will move, when it fails it will not appear correctly. If the mask is cleared before it is set then it is shown correctly.
