--- Comment #32 from Ruslan Kabatsayev b7.10110111@gmail.com --- For users to be informed, this upstream bug has now been reported to Mesa (after so many years it's still not fixed there): https://bugs.freedesktop.org/show_bug.cgi?id=97351
This should affect all Mesa-driven GPUs with software T&L (but swrast isn't affected for some reason). Might also reproduce with RADEON_NO_TCL environment variable set for radeon, r200, and r300g, but I have no ATI/AMD GPUs to check.
