7.5M0 bug: breaks Miracast cloning mode and excessive drain on connected standby.
Although the 7.5M0 drivers are nice and fast on my Dell Venue 8 Pro, I just discovered a couple of bugs. With the drivers installed: miracasting to a wireless display does not work in cloning (mirroring) mode. All other modes work fine. There is also an excessive power drain during connected standby. The powercfg /sleepstudy says that it is due to the Intel Graphics not shutting down properly. Once I uninstall the Displaylink driver, everything returns to normal, Miracast cloning works and connected standby has a very low power drain.
Hope you will be able to resolve this, thanks. |

Hi,
The connected standby issue is being investigated. Can you attach logs for the miracast issue? What make and model receiver are you using? Thanks, James |

I am using the Netgear Push2TV PVT3000 adapter. The debug log is attached here. The Displaylink adapters were not connected when I took the log, only Miracast was operating in extended desktop mode.
Thanks for looking into this matter. |

Hi,
I'll try and reproduce this - can you please attach the logs with Miracast set to mirror? Thanks, James |

Well, that's the whole point. It doesn't go into mirror mode. I click on "Duplicate" in the charms and nothing happens. If I click on "Clone" via the Intel Graphics menu or options panel, nothing happens.

Hi JamesH, have you managed to replicate the Miracast mirroring bug ?

BurningOrange -
Was wondering if you could confirm, did clone mode work with 7.4 drivers and only recently broke with 7.5? I am experiencing the same problem, but I've only ever had the 7.5 update installed. If 7.4 worked with cloning and you were able to mirror screen, I was considering finding a way to go down to that. |
