STR: 1. enable lockscreen from settings app. 2. launch a "fullscreen" app which doesn't contain statusbar. (e.g. camera, gallery, etc) 3. press power button to turn off the screen. 4. turn on the screen by pressing power button again. 5. the statusbar disappears!

It's actually caused by Bug 1016822, at least this is what I can bisected out. Since it's an old bug and revert would be failed, I need to check it manually.

Mark keywords to make sure I didn't bisect out the wrong bug.

returning to comment 2 request for regression-window.

We should really also get a blocking triage analysis on this bug as well. If it's non-blocking, then it's not worth getting a window on.

Nomming as a blocker - Users will often just check the lockscreen for the purpose of looking at the status bar. Scenarios are to ensure that their alarm is set (as indicated by the alarm icon), to check their battery status, to ensure they have power-draining features turned off (blue-tooth, wi-fi), etc.

This bug did not appear in the push-log, so it might not be the cause

Kevin - out of that pushlog, your bug 971552 is the only one that looks like it might affect the lockscreen? Can you take a look?

(In reply to Joshua Mitchell [:Joshua_M] from comment #11) > Kevin - out of that pushlog, your bug 971552 is the only one that looks like > it might affect the lockscreen? Can you take a look? I find it highly doubtful that bug 971552 regressed this. Greg's original bisection of bug 1016822, or potentially bug 1010651 is much more likely as it touches on some statusbar/transforms diffs.

ok. there were a few issues with other visual lock-screen bugs 'interfering' with getting a solid regression window so we'll look at bug 1010651 (which is in this pushlog) and if that is a dead end we'll go back and try the regression-window process again. (possibly in Buri instead) Thanks for your help / time. Christian - can you take a look in regards to bug 1010651

Sorry, but I'm a little confused about the regression window and the dependency. If this is really caused by Bug 1010651, it has been marked as duplicated. And the duplicated Bug 1016822 has been marked as RESOLVED FIXED, therefore there is no bug need to be fixed or has been reopened.
