empty view ports after latest update

[CJRenders]

With the most recent daily build update I started getting black/empty viewports. The scene would be visible once opened but as soon as I change to a different view or navigate the scene it turns black. After my queue finishes im going to reinstall corona without any daily builds. Has anyone else experienced this and know a fix or what might be causing this?

Hello,

I experienced something similar via TeamViewer or Screen Sharing, but I suppose this is not the case.
Does the same thing happen without Corona installed?

Thanks,
Jan

Do you have opengl corona materials active?
Black viewport is usually due to some fuck up with opengl. Check your drivers as well, sometimes I had to update the drivers, and sometimes I had to roll them back. A quick test is to turn off enhanced openGL in the viewport and see if it goes back to normal.

Can you check this with another renderer set as the default? My guess is R25 being R25
