Vegas Pro 21.0 build 315
Windows 11 Intel i5-14600K 64gb RAM Arc A770

I have been editing with this configuration very successfully for quite some time. Been a while since I last worked worked on a project, kicked off a new one and now my preview screen flickers a black screen. Changing preview quality has no effect. All drivers up to date. Any ideas?

Is the issue media specific? If so, share MediaInfo?

It does not appear so, as previous projects that did not flicker, now flicker.

Any other clues?

Does a reset help? https://www.vegascreativesoftware.info/us/forum/faq-how-can-i-reset-vegas-pro-to-default-settings--104646/

Haven't tried a reset yet. I will today. I don't have much customized.

Tried rolling back my graphics card driver to a date prior to my last successful project. No change. Uninstalled the most recent Windows update, no change. However Windows11 24h2 recently installed, and I can't roll this one back. Any ideas if this could be the culprit?

Worked through my project without the second one monitor preview. Ran my normal render settings and Vegas is not utilizing my GPU. What would normally have taken. 10 minutes is going to take over an hour. I gotta figure this out.

This just started happening. Using  VEGAS Pro Edit 21 with windows 11. When I try to use "video preview on and external monitor " I get screen flicker on the monitor I am directing it to. I am able to use other Apps with no problems. I am able to undock using the Video Tab to the drag to the monitor but have to manually resize. I reinstalled 21 and the trial of 22 and got the same results even after restoring the default settings.

I still have the preview flicker problem.

Fixed my GPU rendering issue by updating my driver.
