Display glitch when switching viewports


I’m experiencing a rather annoying display glitch when changing viewports. This started a few days ago.

Display refresh seems to take a little bit of time and I have blinking objects when I move them in a viewport and switch to another one.

I cannot reproduce this on another computer on W7 so I think it’s more related to my setup rather than Rhino itself. It does happen every time though on this machine, both in R7 and RWIP.
Hard to screen capture however, but I got that one :

Drivers are up-to-date and screen refresh is at 144Hz - tested with 60 but then navigating in Rhino is a disaster and it doesn’t solve the issue.
Also tried to bump up the dynamic redraw setting in Rhino options, no change.

Does any one have an idea on what could cause the issue and a way to solve this ?

Another case where this happens : trimming in a viewport in Wireframe then switching to a Shaded wireframe.
We can clearly see that the object is shown untrimmed and refreshed a split second after - but not quick enough.

I cannot reproduce that here

So it did not happen after a change in Rhino? I know this is already a couple weeks back, but do you recall any other changes made to your setup?
