> well, the question is why radeon is slow in thase case for (SHM)PutImage.

Is it really only doing SHM PutImage stuff?   I've got a bug where I can
reliably trigger [drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -12!
from just scrolling around and zooming  in Google Maps on Chrome (chromium
browser daily builds on Maverick).   While I can reliably trigger this (every
time) in KDE with Desktop effects, I have also managed to trigger it on Gnome
with out desktop effects.

If Chromium was only using PutImage would it really trigger stuff like that
from drm?
