I've been putting up with the same issue for almost a year with OOTPB 16 until I found this fix from one of the posts in the forum.
(Unfortunately, I can't remember anymore where I found it.)
The fix is actually quite simple and you might like to try it.
Change game
SETTINGS of the following
3D & Facegen settings to the ff.:
1.
3D features / OpenGL support - set to
Enabled
2.
OpenGL Mode - set to
Use OpenGL only for 3D
3.
OpenGL Shader Mode - set to
Enable OpenGL shader (better 3D graphics)

Restart the game.
By the way, the same fix also works for OOTPB 17...
