I have sent a message to Boris but just thought I'd try the CC forums incase someone has experienced or can recreate the issue.
Product: Boris FX
Version: 6.2 (Also happened with 6.0.6)
OS: MacOS X 10.7.x
Host Application: Avid Symphony 184.108.40.206
I put Avid FX plugin on a layer above a clip in the timeline and put some plain text in and save it, looks fine but then when I render it get's a green cast across it. It's almost like it's clipping the blue highlights.
