Git commit fda53d8253b5583d253bd35315229768fd414578 by Xuetian Weng, on behalf of Weng Xuetian. Committed on 31/10/2022 at 22:42. Pushed by xuetianweng into branch 'master'. Fix blur/contrast for X11 window if Xwayland is not scaled. X property from X11 window contains X native coordinates. Need to apply transform to use them in the effects like blur/contrast.
