Hi, I have a window that uses windows shape for my application. I'm trying to do a full screen 'glint' effect over it but I get some horrible glitches where the window shape is transparent. (See video).

Is there any way to get around this? Or some other way to do it maybe? I've tried most (if not all) of the different shader settings but they all do the same. I'm using 292.5 (Direct3d 11)
