I have glamor 0.6.0 - is that current? (Gentoo doesn't have anything newer, it seems)
That's the old standalone glamor tree. Please try glamor from xserver 1.16 or newer.
Do I need to restart X to try this? xorg-server 1.16 is not considered stable, and I encountered actual problems with some version post-1.15.1 (sorry, don't remember what) - so I'd rather avoid the upgrade if possible..
