I can confirm this strange behavior. The programs given in the package vtk-examples can reproduce this issue. (as an example, /usr/share/vtk/Rendering/Python/rainbow.py)
The problem occurs on my laptop (radeon mobility 9600) and desktop (firegl rv370) This problem is not specific to Feisty, as the 8.32.5 drivers also give the same issue on Edgy Eft. -- fglrx-driver behaves strange in 8.32.5, works fine in 8.28.8 https://launchpad.net/bugs/76383 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
