[vtk-developers] minimum Mesa Version for VTK?

Building on your idea, what about a "recommended" OS Mesa version for 
each VTK release? One idea might be to use the newest OS Mesa driver 
available at the time of the previous VTK release. that way there would 
be one full VTK release cycle of dashboard coverage. If major issues 
were uncovered or VTK released quickly i think it would be fine to hold 
the mesa versions back for a cycle. I know this is more work maintaining 
the dashboard systems but it would be beneficial to have that coverage 
and testing for PV (and other hpc vis tools) which often rely on OS Mesa 
when running on hpc systems.

not a bad idea, it's old but at least it's still available on Mesa's ftp 
server ;-)

Over the past couple of days I've been incrementally testing older OS 
Mesa drivers. The test failures start pre 8.0.5. It looks to me like a 
genuine Mesa bug. Rather than introduce a kludge to make it work I plan 
to disable FBO's with OS Mesa and Mesa < 8.0.5.
