[mir][maguro] white screen during autofocus after phone has been rotated

[Chris Gagnon]

Description:
[mir] a white screen is shown during autofocus after phone has been rotated

Steps:
1. adb shell touch /home/phablet/.display-mir
2. adb reboot
3. Open camera app
4. Rotate screen
5. Move camera around at different objects or tap the screen to autofocus

Expected results:
Camera does autofocus without interrupting picture

Actual results:
Camera does autofocus, but the screen flashes white first

Additional info:
This only happens with mir enabled.
You must rotate the screen once for this to take effect.

I tried to rotate the camera left, right and upside down, but cannot reproduce this defect with build 80 (20131003.2) If you can reproduce with this image, could you verify the steps in the test case?

[Chris Gagnon (chris.gagnon)]

I have the same results with 20131003.2, but now I don't need to rotate the screen for the flashing to happen. I am using a maguro, maybe that matters.

Steps:
1. phablet-flash ubuntu-system --no-backup --channel=devel-proposed
2. adb shell touch /userdata/.writable_image
3. adb shell touch /home/phablet/.display-mir
4. adb reboot
5. open camera app
6. use autofocus, tap the screen so the circle moves

I've attached a video

otherwise its not something we'll adress

[Jean-Baptiste Lallement (jibel)]

I cannot reproduce on Mako Utopic build #85

setting to 'invalid' as I am not allowed to set it to 'won't fix'
