Forums: 

Basically I successfully installed Debian 7.2.0 on VirtualBox, but when I run simple OpenGL demos (like the snowman demo by 3d Lighthouse) i have a bug

the viewport don't refresh! (well it is refreshed only when resizing the window).

I already asked on Virtual Box forum without getting answers :/.. Any help is wellcome for helping fixing the problem (I'm not sure this is the right section of the forum in that case I'm sorry).

Edit:

I can't install Debian directly on my laptop because:
- No CD drive Sad
- I have internet key that installs only on windows Sad
