    I just tried it on Unity 2018.4.6 (LTS) on a Windows 10 PC with a HTC Vive pro connected. The Display on HTC VIVE flickers constantly when two displays are on.

    Is there a resolution to this issue?

    I still see this on 2019.1.f02. Seems like anything rendering via OnGui is affected.

    This is literally still happening? Is this not even being looked at?
