Hi.

I'm an owner of older Vegas Pro version and decided to try the demo version of Vegas Pro 19.

I did a little bit of testing, and noticed there is a continuous problem with UI rendering of (at least) the Video FX tab.

- Sometimes moving mouse cursor over list items will leave item rectangle rendered with some garbage, like a stretched piece of text.

- Alt tabbing between Vegas Pro and any other window will leave the whole Video FX tab rendered blank occasionally.

- Sometimes some of those eye icons of effect preview will cover the whole window when alt tabbing back to Vegas Pro.

I have seen similar UI rendering issue maybe once with some free software on this computer, but not with any other software. This is a custom built PC. This isn't rare, I get it after a few moments, in less than 30 seconds if I try doing anything it FX tab.

Example of rendering error (should be obvious):

Specs:
- Windows 10 professional
- RTX 3060 Ti (latest Nvidia display drivers)
- 64 gigs of ram
- AMD Ryzen 7 5800X CPU

Is there some option to tweak or is this a known issues?

I don't remember having any such issues with version 14 which I'm still using occasionally.

Thanks in advance!
