I have a two GPU setup, a desktop computer with both an AMD and an Nvidia card installed. If I have the display port plugged into the Nvidia card and run the DX12 application on the AMD, or vice versa. I get this error:

ERROR: ID3D12CommandQueue::ExecuteCommandLists: Non-simultaneous-access Texture Resource (0x000002C0F862A400:'RTV_1') is still referenced by write|transition_barrier|assert_read GPU operations in-flight on another Command Queue (0x000002C0EDCDE330:'Direct command queue'). It is not safe to start read GPU operations now on this Command Queue (0x000002D2EF9E1DB0:'Internal DXGI CommandQueue'). This can result in race conditions and application instability.

I got an answer from one Microsoft DX12 programmer that this is a DXGI bug, but I cannot find any place to report the issue. Is this the correct place or do you have something similar to issues for DXC but for DX12/DXGI?
