I agree that the glyphs no longer have the problems i was describing, so this bug specifically could probably be closed. however, when mousing over the icons, the usual subtle gnome mouseover highlight visual response was replaced with jarring, tearing visuals. i'm not even sure how to capture them, but the background of the items turn weird colors and have artifacts strewn around in them. > Additionally, it would be interesting to know whether 3D hardware > acceleration works on your laptop ?? i don't know of any laptop related to this bug report.

What would be the best way to go about testing and reporting whether 3D hardware acceleration works or does not work in this case? --dkg
