FCP X freaking out

Have had FCP X for several years and it's been great. But now it's freaking out - no cursor control/flickering/arrow changes to a crosshair - presumably Yosemite upgrade has something to do with it, or perhaps the long timeline of 3 hours. Zooming in seems to start it.....Have never had problems before. Will see if there is a preference reset possible for starters.

Tried deleting prefs - looked to have worked but zooming in to timeline for audio adjustments caused major freakout - see screenshot...

Not seeing a screen shot. I wouldn't use 10.10 until 10.10.1 at the earliest on a three hour project.

Am using Mavericks 10.9.5 actually, my mistake. Will try and insert screenshot again..

I'd suspect some sort of GPU corruption.. Installed any new software/drivers lately?

Just one bit of software, have trashed it to see if that helps. Just noticed that a HP printer driver was updated today by App Store automatically. Will see if I can remove it as the bug is still consistent with the zoom-in on the timeline audio forms

Looks like s graphics card problem processing the media. What is it?

4k from a GH4 -H264 codec 24p 4096 x 2160 - not had problems with it before on a smaller project

Removed the HP printer driver - so far, no more freak outs!

Thank you for the update. Interesting to hear how a printer driver can screw up an NLE.
