[M-dev]More weird Rubicon errors

[<Al...@ao...>]

This time I tried to save memory. I set all the textures to RGB 2222 and 
set the screen colors to Thousands. It didn't work. OpenGL dropped all 
the textures (but never froze) and I got horizontal frame tearing. (How 
is that possible? I thought frames were drawn vertically.)I turned off 
OpenGL, played some more and it froze. My final conclusion is that the 
Rubicon Network Pack is cursed.
