Bug Description

I set the BQ M10 device in Desktop mode yesterday evening.

After that i used the tablet mode. Then i went to sleep. As i turned on my device i got the flickering in the video.

I restarted the device. The flickering was gone.

The device is on the image version: r108

I saw that once, too. It's very unlikely unity8 has to do anything with that, more like the driver gets in a bad state when it suspends with an external screen or so. It's as if it has lost synchronization or something.

Adding Mir as the component closer to the driver/hardware.

Yesterday i had the same problem again. But this time without being in desktop mode before.
This time i used the tablet mode like so often before.

Then the weird thing in the video happened.

After i suspended the tablet 2 times (short press in the right top button) the tablet worked the normal way.

Won't fix in Unity8 because Unity8 is unsupported.

As for Mir, there might be some residual issue but it's not clear. So let this bug expire organically...
