Grey Visual Artifact

Hello,
Has anyone found a solution to this Visual Artifact? 1 map out of 2, I have my screen switching sometimes between "normal" and "all grey /partially grey" while mapping (like flash to normal/grey).



I have a recent PC (4070ti/13600K).
I've done all the usual checks (drivers, config, PackCheck, ...).
I've tried Vulkan, dx11, dx12. With all possible combinations of graphics parameters (Dynamic culling, res, multithread, ...), all in low.
With or without MTX.

But in every case, I get this visual artifact. Thanks in advance for your help/tips.

I get the same issues here when mapping. It can get pretty aggressive at times and is starting to strain my eyes.
