 That looks like it paints outside of the actual window area (when a window 
moves only its old geometry is marked to be repainted, if something remains 
then it's probably outside). It may be some rounding error somewhere, or 
possibly the rect adjusting in BlurEffect::updateBlurTexture(), I don't 
understand that code much.
