So I'm working on this composition with a lot of 3d layers. Sometimes when I switch views, the hand tool stops working completely, for no apparent reason. I hit space, the hand icon still shows, but nothing happens when I drag the cursor. Then after a while it starts working again, for no apparent reason either. It's driving me nuts.
I've already tried resetting the preferences, to no avail.
My specs :
i5-3330 @ 3.00GHz
6 gigs of RAM
NVIDIA GeForce GT 620
1 To HDD
Could be a cache issue or your graphics card not flushing its buffers. Turn off the performance cache in the prefs and update your graphics driver....
