Closed Bug 1133518 Opened 5 years ago Closed 5 years ago
Most of the applications (like Gallery, Settings or Email) in B2G display blank and can't be scrolled
STR 1. Go to Settings, then Bluetooth. 2. Observe the white screen. This prevents the smoke test to pass. Does repro on the current 3.0 but not on 2.2. Does not repro on the build where bug 1132741 was spotted. [Blocking Requested - why for this release]: Smoketest regression. Regression window wanted.  https://moztrap.mozilla.org/manage/case/6071/  Build ID 20150216010344 Gaia Revision f0b93e0668ef9565bd6f050b15b4f794d59feb65 Gaia Date 2015-02-13 13:13:27 Gecko Revision https://hg.mozilla.org/mozilla-central/rev/e0cb32a0b1aa Gecko Version 38.0a1 Device Name flame Firmware(Release) 4.4.2 Firmware(Incremental) eng.cltbld.20150216.050451 Firmware Date Mon Feb 16 05:05:02 EST 2015 Bootloader L1TC000118D0  Build ID 20150216002503 Gaia Revision ea64caf6d4ab03fc4472eca9f41f20d651d55fa9 Gaia Date 2015-02-13 05:27:43 Gecko Revision https://hg.mozilla.org/releases/mozilla-b2g37_v2_2/rev/62c80c92b39e Gecko Version 37.0a2 Device Name flame Firmware(Release) 4.4.2 Firmware(Incremental) eng.cltbld.20150216.040540 Firmware Date Mon Feb 16 04:05:52 EST 2015 Bootloader L1TC000118D0  Build ID 20150212064620 Gaia Revision 2a2b008f9ae957fe19ad540d233d86b5c0b6829e Gaia Date 2015-02-12 07:44:13 Gecko Revision https://hg.mozilla.org/mozilla-central/rev/81f979b17fbd Gecko Version 38.0a1 Device Name flame Firmware(Release) 4.4.2 Firmware(Incremental) eng.cltbld.20150212.102136 Firmware Date Thu Feb 12 10:21:46 EST 2015 Bootloader L1TC000118D0
One thing I forgot to mention, if you go to the task manager you're able to see the bluetooth page again. If you tap where the buttons are supposed to be and then go back to the task manager, you can see the state of the buttons changed.
That's 100% what I have documented in bug 1132741 comment 21.
I could confirm the issue I mentioned in bug 1132741 comment 22 looks exactly like this.

What do you think David?

This bug somehow blocks us development and testing.
I tried to do the backout but I got a conflict and then a compile error. Hence, I checked that bug 1075670 was the actual cause of the issue: I checked out gecko at 5186614bfe01 => Can't repro the bug Then I checked it out at 17a3125a2f05 => Repro. Bug 1075670 is the cause of the issue. David, could you back bug 1075670 out?
Making the summary of the bug more general, per its dupe.
Summary: Settings -> Bluetooth shows as a blank page with just the title displayed → Most of the applications (like Gallery, Settings or Email) in B2G display blank and can't be scrolled
I backed out bug 1075670 directly on m-c using gsvelto's patch. https://hg.mozilla.org/mozilla-central/rev/4bb425001d8a

Hi Johan, I'm looking into the issue here but I'm getting somewhat different results. When you said that the Bluetooth page was blank, does that mean completely blank? Or 'missing elements'. Here's what I've seen: Without the patches, you can go to Settings->Bluetooth and see the image in the "no-patch" image attachment. It has all of the screen elements. With the patches (manually applied to trunk), I get the image in the "patched" image attachment. Clearly, its "missing" the "Paired Devices" and "Devices in the area" and "Searching for devices..." sections. Looking over the source code (and reading the screen), I realize that is by design. The patches in bug 1075670 actually fix a longstanding bug that was not updating the visibility of those elements but, when I "Turn Bluetooth on the view devices in the area", all of those elements reappear. Indeed, they flash on screen for a fraction of a second before disappearing when I first navigate to the bluetooth page (this is clearly a bug). The other apps in the title (Gallery and Email) also look fine to me but I'm not sure what I should be looking for. I definitely don't see the issue in bug 1132741 -- I think its unrelated. I am using a Flame-kk on a Flame device.
Looks like you're using B2G desktop, which may not have the same results as on-device. On my current master build on a Flame device I see the "with patches applied" version of the screen, even though I don't have your patches.
Thanks. I'll see if I can get the blank screen now.
