Get an annoying glitch during playback that comes and goes with Vegas v17. It occurs while transitioning between segmented clips that are adjacent to one another on the timeline. Kind of hard to capture because usually once I see it and replay that section... it's gone. But I got lucky when it just happened while I happened to be capturing my screen. Below is a snipit of the capture:
Btw, doesn't seem to happen when I'm doing short projects. In the project above, I was over an hour into the show when it first happened. What I usually do when I see this happen is to drop a marker at the troublesome transition. On the theory that it's a Vegas clip buffering issue. Because the glitch occasionally creeps into a render but playing over the troublesome transitions right before the render keeps it from spoiling... this has worked every time so far. Btw, doesn't matter what format I'm rendering to. Short mp4 or long intermediates. It's most annoying when it happens while doing multi-hour renders. Below is a snipit of a rendered mp4 clip with the glitch:
This happens to me on occasion on a variety of systems and seems to have started with v16 where it happened more often. In case it relates to my camera clip format, here's my mediainfo:

If anyone has any suggestions on any Vegas config settings, internal or otherwise, I'd sure love to give it a try.
