What hardware is this being tested on?
Can you attach a picture that was taken that exhibits the problem?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

I've seen this on krillin yesterday, too, can't reproduce now in latest rtm-proposed image.

I can consistently reproduce this bug. I am on the ubuntu-rtm/devel channel. Further information including examples of the bug and a full description can be found here:

[Michał Sawicz (saviq)]

Yeah, I had the same on mako again. The weird part is that the photo displays fine when it scrolls away to the right, but not later in the gallery or the photo roll.

Hey everyone, I'd like to know if it's still reproduceable for any of you with the latest Ubuntu 15.04 on the Nexus 4. @Adam, @Dario @Howy?

[Florian Boucault (fboucault)]

Seems to be exactly: https://jira.cyanogenmod.org/browse/CYAN-2644

[Florian Boucault (fboucault)]

Could be somewhat related to https://jira.cyanogenmod.org/browse/CYAN-508

Flash used to be disabled in continous focus mode on Nexus 4: https://code.google.com/p/android/issues/detail?id=52910

Interesting changes in AOSP that might be related:

Stumbling into this in the wild on mako r297, not able to reproduce immediately. This was only happening with flash on FWIW, nothing relevant in camera-service logs.

[Allan LeSage (allanlesage)]

Stashing some logs, let me know if any would be helpful.
