Public bug reported: Dear Friends,
I have an intel 855GM graphics card with the last 2.7.1 drivers. Maple 10 and Mathematica 7 3D-plots are in practice unusable/invisible. I've tried with several xorg.conf configurations, i.e exa/uxa with/without tiling, with different migration heuristics and even with different drivers versions (2.6 and 2.7) but the problem persist. I think it's due (again) to this damned graphic drivers, because the problem does not show up on Nvidia/ati cards. I would say to Brice Harrington that the problems with the intel graphics drivers are still far to be solved completely. Even if with the new driver 2.7.1 3D performances are acceptable, 2D is still very slow. Just compare Gimp's or Firefox's performances on XP and on Ubuntu, the differences are visible at eye. Its sad to see native Linux applications running faster on Windows!! That's what people will think: "Linux: You can't even plot a 3D graph."
