I have found a bug in Vegas Pro 16 Build: 352 where full-screen monitor preview will crash Vegas Pro. I was able to resolve the issue by rolling back to version 307 and found that full-screen preview was working again.
First steps that I did when troubleshooting
Have Tried:
Updating Windows 10: Version:1809 Build:17763.253
Uninstalled and reinstalled video driver,
Tried turning off GPU acceleration didn't fix it.
Tried previewing middle monitor with same results. Tried 1st monitor, and while it worked, it would end up covering my timeline so it's not really a fix
Tried: Doing a clean uninstall of Vegas Pro 16 with Revo-uninstaller and then reinstalling Vegas Pro.
FINAL FIX: Rolling back Vegas Pro 16 to build #307. Problem resolved itself. I believe that 352 is bugged with the full-screen preview button.
BUGGED VERSION: Vegas Pro 16 Build: 352
RESOLVED VERSION: Vegas Pro 16 Build: 307
However, I don't know what is it about Build 352 that us causing the Full Screen Preview to crash.
I hope this helps the dev team, if you need more information, please reply. :)
