Masks failing in previews and exports

[ianmage1]

Here's a preview of my character with all of his masks failing; the irises, teeth, face, chin, and shading are clearly amiss.

This happens more often than it should. Restarting the software usually does the fix, but, as of right now, these masks are consistently failing. Sometimes, during an export, the masks will work on some frames and fail on others. In most cases, the opacity and blur settings of the layers in the masking groups will also fail.

This bug doesn't occur consistently, but I'm never assured that my animations will render as they're supposed to. I've been trying to avoid this bug since AS8, but it always comes back to haunt me every now and then... maybe it's a hardware issue?

Has anyone else had this problem?

My first guess would be that your computer is running short on RAM while rendering.

@synthsin75 I think you're right. Thank you very much! I won't be bothered by this anymore.
