Wrong PixelShader used [XboxOne]

Hi

Rarely/Randomly a StaticMesh is drawn (permanently) with a wrong color or lighting.
The issue toggles when we disable/(re)enable the parallel algorithms r.RHICmdUseParallelAlgorithms 0/1 (or using r.RHICmdBypass).
With PIX we did two GPU captures. So we noticed that the “broken” Draw simply uses a wrong pixel shader (textures, cb and VertexShader are the same as in the correct capture).
We suspect a thread issue/cache
Any ideas to start investigation ?

Hi Nicolas,

It appears that you have UDN access so I would highly recommend that you post your questions there instead.
