This is exactly one of those problems I described in the thread "general cinelerra performance". > My Card is a Gforce 7800 with the latest NVidia drivers. My card is a GForce, too. I think it's GForce MX 4000 together with NVidia's binary drivers. My suggestion is that all people with openGL-troubles post the card model and driver. I wouldn't be surprised if most of them (including myself) are using NVidia cards. There might be something fishy with their closed-source drivers.
