Can't Scrub Timeline

I can click Play and footage plays fine. I can click to any point in the timeline fine. I can track with no problems. What I can’t do, is scrub the timeline at all; it isn’t slow, it just hangs. This is true for any resolution footage. If I try to scrub the playhead, Mocha AE freezes. I’m fine on RAM, my graphics card is robust (Nvidia K6000), running After Effects CC 2014. Any ideas would be most welcome.




Hi Mike,

What are you using to scrub? A trackpad, tablet pen or mouse?

Can you try turning on “Disable offscreen buffers” in your mocha preferences under the Open GL tab and restart mocha to see if it helps?
