I would also like to add: Blank window with 3D if resolution is set to 1680x945, however, no matter the resolution, GNOME 3 will go into fallback mode.

Scratch that, I was in force fallback mode. GNOME 3 works at other resolutions just fine. If you disable page flipping, does that work around any of these problems? As discussed on IRC, the issue is the 945 height of the panel. There seems to be somewhere in the ddx or mesa where the height is not aligned properly. The problem can be reproduced by manually setting a mode with a height of 945. Change the mode to 1024x768 for example allows rendering to work correctly.

Created attachment 47078 [details] Xorg log glxgears and openarena seem to be blank screens while nexuiz appears to work fine until you exit. When exiting nexuiz, the screen 'froze' if you will. I could switch to a VT, but nothing was happening in GNOME.
