Summary: green screen when alt-tabbing

Details: here's a strange bug, that's present in both beta6 and cvs0125.
when using the precompiled binaries (haven't tried from source),
alt-tabbing from the Win32 OpenGL client and back to it results in the
entire picture being offset downward. the effect is cumlitive, too, so
after two or three alt-tabs it's unplayable.

I'm using a 3d prophet II MX (geforce chip) under Win2K.

ah, yeah, that worked.

although, -brokenpopup causes the Win32 titlebar stuff to show, which
forces the bottom twenty pixels or so off the screen.

I checked, and the 'green screen' occurs in several flavors of GLQuake, so
I assume you're right in that it is a driver problem.

I'm using the 6.31 detonator drivers from nvidia, if that helps any.

Looks like driver bug. Get latest binaries
http://quake.sourceforge.net/files/newtree-win32-bc-current.zip (or compile
your own from current CVS) and try with:

qf-client-wgl -brokenpopup

I'll try to create workaround bit lateron, but right now that switch is the
ONLY way of alt-tabbing with borked drivers.

Probably driver issue. I remember having same kind of effect with some
drivers. I'll try to reproduce.
