Might be a dupe of bug 998929. Please work on a regression range.

I too think this is a dupe of bug 998929 or wherein pretty much the same problem.

It's too reproducible using https://developer.mozilla.org/samples/domref/fullscreen.html. After exiting full-screen, the toolbar completely disappears and the page is bumped up and the underlying canvas is shown behind the page as a different background colour.

Kats, do you think this is the same problem as bug 998929?

If the range in comment 2 is right then it's likely not the same problem as bug 998929 but I can't say for sure without investigating. Also there's nothing in the range in comment 2 that would explain this behaviour.

Are you sure this is an fx-team branch regression?

[Cristina Madaras, QA [:CristinaM]]

Is not an fx-team branch regression. I verified this again and the pushlog is: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=611698b4a246&tochange=4da3e21a0e5f
Sorry about that!

Seems that I had some problems with Mozregression, it didn't work properly and gave me some errors. After reinstall I investigated again this bug and this is what I found:

1.
Build from 2013-03-07 ee4879719f78 - video looks good in both normal and full screen mode.
Build from 2013-03-08 cb432984d5ce - when entering in full screen mode the canvas is displayed at the top of the screen, going back at the normal screen looks good.

Pushlog: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=ee4879719f78&tochange=cb432984d5ce

2.
Build from 2013-07-11 dde4dcd6fa46 - in full screen mode the canvas is still displayed at the top of the screen.
Build from 2013-07-12 b44898282f21 - in full screen mode the video looks good, going back at normal screen, sometimes the top of the page gets cut-off as if the page is underneath the title bar, sometimes the canvas is displayed at the bottom of the screen and the toolbar disappears.

Likely bug 853986. Maybe bug 877602 but I doubt it.

I won't be getting around to this anytime soon. Wes might be a better person to look at it.

(from bug 1135780) I can only repro on my galaxy chat with dynamic toolbar enabled.

Comment 14

[Kartikaya Gupta (email:[e-mail])]

qawanted to retest on the latest nightly. I think it might be fixed with bug 1180295 and bug 1197233 but in my local testing I think I saw it once still, so I'd like to get a second opinion.

Comment 15

[Kevin Brosnan [Ex-Mozilla]]

Works for me in nightly and can reproduce on Firefox 40. I do have a followup that the video is restored underneath the address bar after exiting full screen.

Filed bug 1198530 for those of you following along at home.
