Engine: IVF cutscenes don't render properly anymore
Prior to 88f90a19 the attached cutscene will render properly, afterwards it will be completely black with occasional white pixels.
Simply place the file in your eduke32 folder and launch the game to see the issue.
Edit: Specifically, the following added code is causing it:
// attached overlays and streaming hooks tend to change the GL state without setting it back if (bpp > 8) polymost_resetVertexPointers(); else glsurface_refresh();
