Ominpresent issue - the following two things occur:
- the HUD will glitch in one of two ways - either all transparent HUD textures will be replaced with a purple matte pattern, or the x,y coordinates of all HUD elements adjusts for a frame or so as if they were on a smaller display, centered at the middle of the camera, causing a warped lines effect. This does not happen always; certain areas are more prone to it than others (free company house seems exceptionally bad)
- during times in which this glitching is occur, the application will occasonionally hang. Anecdotally, it seems to occur when there are many diffuse light sources in the viewable area (spells, glowing enemies, etc). The following (fairly unhelpful looking) log dumps to windows:
