      Drawing a scaled-down pixmap with a circular clipping on windows with window scaling of 125 % does not cover the complete area. Lines within the area a drawn with the background.

      100% and 150% scaling seem to be fine.

      Screenshot attached to illustrate problem. Source code attached as well.
