blinking background render indicator freeze

One of my editors is having frequent lockups in FCPX, and he reports that each time the app becomes unresponsive the background render status blinks between 0 and 100%. The only solution thus far has been to force quit FCP. Is this a known issue with anyone else?

Thanks,

I've had this issue as well.

It is when I am working on a project that has been converted with 7 to X and then it happens if I start working with a particular title sequence. After watching the render indicator flash for a while, I have to force quit, and restart FCP.

FC trys to render, but hen just wigs out and freezes.

In that timeline, Select All, Copy, create a new Project, in that new Project, Paste. Does that help anything at all?

Hi BenB,

I think the project I'm working in is a new project that I copied and passed into. I will double check and start from scratch.

I have noticed that rendering over this one title seems to be a culprit. Not sure why. Maybe Bill can shed more light about his chain of events leading to his issue.

As an update to our situation, I had our editor turn off background rendering and the problem went away.
