When switching between apps by edge gesture, wallpaper is shown in the background. This issue might not appear at first, but I could easily see the wallpaper after switching between apps a few times.

Repro Steps:
1) Update a Flame to 20150520010202
2) Open multiple apps, such as Browser, Contacts, Messages, Email, etc.
3) Switch between apps by edge gesture several times.
4) Observe the gap between apps in the background.

Wallpaper is shown.

Only black background is shown on the gaps.

Gaia is the same so it's a Gecko issue.

Gabriele, can you take a look at this please? This looks to have been caused by the landing for bug 1157030.

I'll have a look but this is rather peculiar. Bug 1157030 hasn't touched anything related to graphics, layout or compositing so I'm unsure how it might be causing a visible artifact.
I've just tested this with gaia 655ecfd48bf67156c36ffacd74441e03a48524c1 and gecko 14245f685eb94baad602e4a849aa47e6f7433073 but can't reproduce. I've tested on a Flame with memory set to 319MB. The bars between apps are always black. I've tried swiping a few dozens of times both normally and very fast but it doesn't seem to make a difference.

This doesn't happen right away, but once it starts happening it happens every time. I've tested on today's 3.0 nightly and it is still occurring. I've found that sometimes let the phone fall asleep and wake it up seems(?) to help with reproducing. I have Phone, Messages, Contacts, and Settings apps opened. I swipe slowly but not sure if it makes a difference.
