Dream Air EVO/OpenPort: intermittent SteamVR error 436 #72

Description

@ethanlessiter

I’m seeing intermittent FailedToCreateDirectModeDisplay / error 436 with Dream Air using Pimax EVO + OpenPort.

In the failed state, only 640×480 at 60 Hz is enumerated and Pimax reports invalid numModes 5, expected 10. After physically power-cycling the headset, 7104×3840 at 90 Hz returns and the video becomes stable with the panel on.

CustomHeadsetOpenVR registers the HMD in both states, so this may be a lower-level display-mode or hotplug issue rather than a driver failure. I’ve also contacted Pimax support.
