Landscape mode is the default rendering mode (it's called normal), anything
else causes the X server to create a new frontbuffer and render with a
transform onto this rotated frontbuffer (this process isn't backbuffered last
time i checked). Everytime the X server receives "damage" on the "normal"
frontbuffer it will update the rotated frontbuffer. This transform happens
outside compiz/opengl (which was used to get the vsync). This is just a generic
story, not sure if this is easy to fix for amd hardware.
