Thanks for the bug report!

(for quick reference)

Analysis: Might be a wrong render state, or z-fighting since the skybox is rendered without depth testing. Should check if it happens without RTX as well, might be an artifact from dxvk.

I checked to make sure this doesnt happen using other renders naturally, and I couldnt get it to flicker. I tested using the following renders.

Kentie D3D10: https://www.kentie.net/article/d3d10drv/

CW OpenGL: https://www.cwdohnal.com/utglr/

I will test using DXVK next and see if it occurs.

I just installed DXVK 2.4 and couldnt get the sky to flicker. I started up Deus Ex and tested using Kentie D3D10 and Echelon after installation (it copied over d3d9.dll file).
