Why "won't fix"?
On my ASUS eeePC 1005P (Ubuntu 12.04, 3.2.0-24-generic) I can reproduce
this bug. The internal display has 1024x600 resolution. I plugged in an
external monitor (resolution: 1920x1080) and arranged it with gnome
display setting horizontally. The result is the described slow display
rendering. If I arrange the display vertically everything is fine.
Then I tried the same after activating the plugin ("Copy to texture") in
ccsm. I restarted my mashine, arranged the window horizontally but the
problem is still there. "xrandr --output VGA1 --right-of LVDS1" has the
same effect.
$ glxinfo -l | grep GL_MAX_TEXTURE_SIZE
GL_MAX_TEXTURE_SIZE = 2048
