Picture of the glitch/bug.

On some rare occasion, when waking up the phone from sleep mode, it's possible to notice a visual glitch on the bottom half part of the screen.
This glitch is having very light "movement" on the buggy part , it's not really fixed/frozen. Even if the upper part of the screen looks normal, this part is a bit compressed, flattened on the height part.

Having the screen to sleep again and waking it up will result in the bug/glitch disappearing.

Picture was taken on a Flame with latest build:

Build ID               20150504160201

However it was noticeable at least another time some time ago, with older builds.(weeks ago)
Clément, how did you update the rom? full rom update? or only gecko and gaia update?

From the symptom, it seems not gecko bug. It seems like driver level bug.

I can't remember how the update was done at that time, but most of the time : a base image was flashed probably weeks ago, and then updates where done either with OTA if available (OTA not freez) and not broken, by using shallow_flash.sh from the QA repo otherwiser to flash a new Gecko & Gaia.
