Video gets destroyed rendering a crossfade transition. Is there a fix?

[IngramNP]

Any time I add a crossfade transition, after I render it, certain frames get destroyed or change colours.

Is this a premiere issue or a computer issue? Anyone else have this problem or know how to fix it??

It's been bothering me for a while.

Thanks

Please tell us your system specs: OS version, Premiere version, amount of RAM, Hardware specs including graphics card

and your source properties and sequence settings...

Looks like it might be a graphics card issue.  so check to see that you have the latest driver for your card...
