SimpleSphereRenderer not working on AMD Vega?

[invor]

On AMD Vega GPUs, Testspheres + SimpleSphereRenderer results in an empty bounding box for all render modes except NG and NGSplat. For these two, the displayed spheres also seem be incorrect.

Also, NGSplat and Simple modes only work after replacing the GL_ARB_conservative_depth extension required by the fragment shaders with the GL_AMD_conservative_depth extension. However, this is most likely a driver bug that we will have to report to AMD.

(Other AMD GPU architecture not tested yet.)

Did someone try this with the enhancements of #248 and #386?

Sergej is able to check this again when he is back.

Reported this issue as bug in the driver to AMD https://community.amd.com/message/2943195

Conservative depth is still a problem. But the issues raised in the first post are resolved with pr #567.

will be solved using the new shaderfactory
