Rhino 5 sr 2 + vray 1.50.22564. Banding

Hello guys,

I noticed a strange issue since I installed the new rhino 5 release.
Please take a look at this picture:

Independently from the configuration - in this case I have High settings - the render show me a sort of banding around my object.
The picture is only a sample, the problem occurs in every cases.

Is it a known issue? How to fix it? Thanks in advance!

I suppose so it’s your TFT screen, that cause a banding effect. Here no banding is visible, looks quite perfect.

Thank you Micha! It was a graphic card issue. After a reboot it is good.
Sorry for the stupid question. Thanks for the support.
