1035266 - Landscape apps leave slivers down the side of portrait apps

Status: RESOLVED DUPLICATE of bug 1034347

(Firefox OS Graveyard :: Gaia::System::Window Mgmt, defect)

Description

[Chris Lord [:cwiiis]]

STR:

1- Open an app that supports landscape mode
2- Rotate to landscape
3- Press the home-button

Expected:

You see the home-screen, and nothing else

Actual:

The home-screen appears, but a small line appears down the top-left edge of the screen.


I discovered this bug during the 2.0 bug bash, but I can't reproduce it using a master build. Seems like this has been fixed and there might be something we can uplift (or perhaps it already has been uplifted and this bug is invalid).

Needs a video.

Attachment: Blank line on the left of the homescreen - Screenshot

This is today's 2.0 homescreen with Cut the rope running in the background. Everytime that this app is running, this blank line is on the homescreen.

By the way, the line on the screenshot is less obvious that the one on the real screen.

I think root cause is here
master: 
https://github.com/mozilla-b2g/gaia/blob/master/apps/system/style/window.css#L675
v2.0:
https://github.com/mozilla-b2g/gaia/blob/v2.0/apps/system/style/window.css#L675

I can reproduce this in 2.1, it's just, for whatever reason, harder.

Hi Etienne,
I saw bug 1034347 has fixed it on master branch, do you mind to take a look at this bug?

[Etienne Segonzac (:etienne)]

Bug 1034347 should fix this, taking and I'll confirm/mark it as duplicate once 1034347 is resolved.

Comment 8

[Etienne Segonzac (:etienne)]

Yep, this was caused by a hack, removed as part of bug 1034347, which is also 2.0+ so resolving duplicate here.

Comment 9

[Benoit Girard (:BenWa)]

Actually I believe this was caused by bug 1027231.
