10900k radeon 6800xt headless - turn off turn on. screen

[hansik]

Hello I have just passed my build with a 6800xt.

.cpu. I9 10900k .mb. z490 vision G gigabyte .gpu. 6800xt tuf

Opencore 9.2 os. Ventura 13.3.1 HeadLess. Accelerated activated. Metal 3 activated.

I had a 2,5k monitor 120 hz.

I had a 570 before and I didn't have any problems.

My problem is the following, I sometimes have a black screen as if my screen cuts and turns back on. This happens for example when I have a 3D game running in the background and I'm on the desktop after an ALt Tab. It's quite annoying.

I checked my Injection igpu which for me are correct. I supposed it could be there. But I miss something... I've attached some screenshots.

This happens to me as well after upgrading to Ventura, was all good in terms of graphics on Monterey.
I haven't done full test yet but locking monitor to your target refresh rate instead of auto seems to fix this issue.
