All of a sudden my Vegas Pro 18 started adding broken frames here and there in the final rendering. It’s always several single frames in random places, displaying either color noise, or one of a previous frames (a distant one) or just black screen frame. I’m attaching a captured example. Notice, that titles in the video have not been affected.
I’ve reinstalled and then updated to version 21 and the problem remained. Interesting that the same Vegas project file renders just fine at my desktop. The bug I’m describing is happening on my laptop. For years I’ve been running Vegas 18 on it and the problem rose just recently.
Any suggestions how can it be fixed?
