VC Viewport stays black


sometimes the VC-Viewport stays black and after some time it resumes. → If that happes first time this behavior repeats itself. → Only a VC-restart fix this issue.

This looks so:

Has anyone ever had this behavior

Thx & Regards

The 3D view is lost (goes black) when the 3D device state is lost, which requires reloading all data back to the GPU memory. This is normal, but it should return once the state is recreated.

If it remains black it might be compatibility issue with your GPU drivers. You could try updating those or e.g. forcing VC to always use discrete graphics.
