OpenGL preventing title cards from showing

[Lotus Gramarye]

For some reason enabling OpenGL in GZdoom prevents title cards for Doom or Doom wads (that have them) from showing up. I figure this has to be some option in the OpenGL options but I have no clue what it might be.

Do you have the correct drivers for your video card installed? What version of GZDoom are you using and what version of OpenGL does your card support?
