+++ This bug was initially created as a clone of Bug #1017389 +++ This bug is created based on Bug 1017389 Comment 12. On flame device, camera preview does not use HwComposer. It is caused by the use of tiled layer. Flame devices uses HwComposer with tiling disabled. It happens on b2g-v1.4 flame and master flame.
Nominate to b2g-v1.4. It could affect camera app's power usage.

Sotaro, on reference v1.4 device (non H/W overlay device, similar to Flame), I see Camera/Camcorder preview frame is using HWC. Tiling is enabled. At which resolution, do you see this issue ? Is it failing at the NULL gralloc buffer check in HwcComposer2D.

Sorry, the problem happens only on 2.0 flame. v1.4 flame does not have this problem. By the way flame's screen size is 480 * 854. And about v2.0 flame, I am going to check again.

Hmm, when I checked it last week, camera preview UI had tiled layer. But today, both on v1.4 and master flame, camera preview UI does not have tiled layer. I close this bug.
