Terrible performance with backing-store enabled.

[Clemens Eisserer]

Hello again!

I have a NVidia GF5200 and to get a bit better performance I enabled
"backing-store" and "save-unders" since I have 128mb graphic-card
memory which would be unused otherwise ;-)

However performance decreases, if I move windows arround they move
really slow or if I open new windows (menus) performance is also
really bad.
Is this an xorg-problem or is this problem more likely caused by the
NVidia driver - since its caused by the nvidia-driver I would send
them a bug-report.
