@thomas.gropp : have you tried upgrading your nvidia driver?

340 is indeed a quite old driver version. But if it worked a few days before we should probably fix the issue regardless since some older NVIDIA cards are struck with older drivers.

This is likely caused by fe4840e or one of the other recent changes in this code done by @fclem. I supposed to initialization of barycentric in overlay_face_wireframe_vert.glsl may need to be changed a bit to work around a compiler bug, dynamically indexing arrays has been a problem before.

@Sharan, normally if something is broken by a developer's commit the same developer fixes it. If you have ideas for how to fix this or other bugs feel free to contribute though.

I know the driver is quite old, but I always had problems with the 390 version.

To help debugging I attached the output STDOUT and STDERR with the option --debug-gpu turned on.
