Comment 5 for bug 980663

Another example is the Unigine benchamark

unigine.com/products/unigine/

If you run this out the box in unity its not only 1/2 the speed it should be the graphics are not actually correct.

However if I enable 'unredirect fullscreen windows' then the speed is normal.

If I go into cinnammon its better, 2d desktops its perfect...

This is a bad bug - surely the 'unredirect fullscreen windows' option should be enabled by default - otherwise newbies will take about 5 minutes to decide to just go back to windows (which they would mistakenly think is twice as fast in terms of 3D speed....)
