On my system, Compiz doesn't draw any windows that are larger than a
quarter of my 1024x768 desktop, if I have MergedFB enabled.  Maybe my
Radeon 7500 just doesn't have enough video memory for larger textures.
Does anyone know, if I switch from a 2304x1024 to 1024x768 virtual
desktop with xrandr, does the X server still keep 2304x1024-worth of
framebuffer allocated out of my puny 32 megs of video RAM?

Compiz works acceptably if I change xorg.conf to use a 1024x768 without
larger MergedFB MetaModes, and disable the "blur" plugin.  Acceptably
but not conveniently -- I miss my Metacity keyboard bindings, my 12
workspaces, and especially my dual-headness.
