Bug Description
Applications using FBOs in a certain way (most notably, Unity) hang for a long time (typically, >30 seconds) after the first modeswitch. There's a similar problem with VT switching.
Attached is the source for a test app. This may be built with ‘g++ -std=c++0x -o fbo-madness fbo-madness.cpp $(pkg-config --libs nux-2.0) $(pkg-config --cflags nux-2.0)’. This requires libnux-2.0-dev, libxinerama-dev, and libutouch-geis-dev installed.
Running the attached test app and attempting a modeswitch demonstrates the unresponsive rendering.
It looks like this might be a regression of the fix in:

@Daniel, any ideas?
