Hi Roland,

Quoting "Roland Hill" <[email protected]>:
The upgraded machine is a laptop with an AMD Mobility Radeon 5850. Everything worked perfectly before upgrading from 12.04.

I still have a desktop running Kubuntu 12.04 with an Nvidia card and the same code base works perfectly.

I have tried OSG 3.1.6, 3.1.7 and 3.1.9 and all have the same problem on the 13.04/AMD machine.

Stating the obvious here, but from your descriptions it sounds like a problem with the 13.04 AMD drivers rather than anything related (and hence fixable) in OSG.

You could verify by installing 13.04 on the nvidia machine.

Cheers,
/ulrich
