Xeon E5-1650 v3 @3.50GHz, Nvidia RTX2080 (with the latest driver), 32GB Ram, Sound Blaster Z. Essentially the UI gets corrupted after a few minutes and eventually freezes. I'm using Vegas to edit audio WAV files at this time. No video files.

We have seen a few other reports like this but we have not been able to reproduce the problem or find a common thread among those that have been seeing this problem. It is very likely a drawing resource issue...possibly a resource not being released. We are monitoring the situation and hopefully will determine the cause soon.

For me as previously posted it happens every time when playing back time stretch video. All my projects going back as far as 2015 with time stretch video fail with this issue. This only happens in V19.

I will try it without the audio just in case it is the audio causing the issue.

Yes it has done it with just the audio track.

I've been trying to reproduce the issue consistently but there is no pattern. I have noticed that this occurs even if the project is never played. I open the project and edit the length of one track over and over (about 50 times over 60 seconds) then the display gets corrupted.

BINGO!!! It's Time Stretch!!! My project has a single audio track that I had to change tempo throughout so I split it and time-stretched each section of audio (min 42% and max 138%). I recreated the project with the same files without any time-stretch and I can't get it to crash. More importantly, I opened the time-stretched project and removed the time-stretching from all the tracks and it works fine.

Hopefully, this helps track down the issue.

If I remove audio is does not do it. If I take off the audio time stretch it does not do it. If I put time stretch back and link audio track to Video it does it.

Great stuff maybe we have isolated at least one cause that reproduces it.

Did you try using another time stretch method and another audio driver?

I used ctrl + mouse to drag the clip (is there another way to try?). My audio driver is Realtek the only one I have. Thanks.

In the Vegas Pro menu Options/Preferences/Audio Device are at least three different choices for the driver selection.

I mean this way to select a time stretch method:

Had this problem since VP18 too. It will happen when the project become super complex. (Comp child, VEGFX, nesting) with more than 100+ media of 4K/FHD.

Reproduce the issue and record your screen.

The only graphical interface issue I've gotten on VP18 and VP19 are the effect thumbnails becoming giant eyes and spanning across the screen. This was on a RTX 2080 Ti and a 3060.

Luckily I don't have your issue, 1080Ti. The UI issue only happens in V19 all previous versions have been fine with time stretch. I will explore time shift/audio options as Marco suggests to see.

Here's a screen capture of my issue. This is an existing VP19 project with one WAV file inserted on multiple tracks with each stretched to random lengths. Everything works fine for a minute but things go bad when the fader indicator turns black. Then the menus start glitching and right-clicking stops working. Eventually, the main menus don't open at all. This capture doesn't show the worst case when the entire VP19 screen turns white and only an end task can close VP19. FYI, I created this video with VP19 with no issues since I did not have any stretching required.

More config info: Dual 1920x1200 screens, display set to 100% scaling, 471.68 video driver version (issue also occurred with older driver 461.72)

In the Vegas Pro menu Options/Preferences/Audio Device are at least three different choices for the driver selection.

Tried it with the three sound devices, Microsoft Sound Mapper, Direct Sound Surround Mapper and Windows Classic Mapper - same issue. Tried different sound stretch option, elastic and classic - same result corruption of UI.

Same exact issue on my end as well. Great find. In need of a fix

How about making a dxdiag and see whether there's problem?

@Yelandkeil  We have four people confirming this bug and a developer acknowledging it. It’s clearly a software issue. What good would a dxdiag report do. 🤷‍♂️

Great news Derek, as long as we know a fix it coming we can wait. Many thanks.
