User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0 Build ID: 20160407164938 Steps to reproduce: I'm using Firefox 46.0.1 I went to the website : http://turnjs.com/#samples/steve-jobs/18 (Turn js flipbook). When you try to turn a page it doesn't show the content properly. I tried this in Firefox 45.0.2 on an other computer and it is working fine. After upgrading this instance of 45.0.2 to 46.0.1 it shows the same issue as on my own computer. Downgrading my own computer to 45.0.2 solves the issue. Actual results: While turning the pages it shows the lowest z-index object Expected results: While turning the pages show the uppermost z-index object.
I think it's already fixed in Aurora/Nightly. Could you download Aurora and confirm on your side, please. https://www.mozilla.org/en-US/firefox/developer/all/
I did, and indeed the "rendering" problem is solved in release 48.0a2 (2016-05-12). However an other problem shows up with the touch interface. Some swiping feature is reacting in a different way compared to 45.0.2 Steps to reproduce: 1) Goto website: http://184.108.40.206/books.html 2) Open the book to page 2 (tap on the right handside of the book) 3) Drag the upper right (or bottom right) corner to another position. The corner should follow your finger movement. In 45.0.2 it does, in 48.0a2 it doesn't. This only applies to touch screens, not to mouse movements.
So there is probably a regression in 48 (or even in 47) with touch screens. As I don't own a computer with a touch screen, could you download the tool Mozregression to find a regression range, please. See http://mozilla.github.io/mozregression/ for details. You can run the command "mozregression --good=45". When you get the final pushlog, paste it here.
As the OP has issues about running Mozregression (due to Chinese firewall), I'll CC someone from QA with a touch screen to test the issue from comment #2 with Firefox 48 and 49.

I could only reproduce this in 49.0a1 2016-05-17 under a Microsoft Surface Pro 2 with Windows 10 64-bit. Dragging works as expected when http://220.127.116.11/books.html is opened with a clean profile. The issue reproduces only after restarting the browser. Afterwards, dragging the book corners will have no effect. 48.0a2 2016-05-17 doesn't have the issue.
Forgot to mention that the regression range points to bug 1180706.

So on FF 47 beta, I see the following behaviour: e10s disabled -> works e10s enabled, APZ disabled -> doesn't work e10s enabled, APZ enabled, no APZ touch support -> doesn't work e10s enabled, APZ enabled, APZ touch support -> works So it seems like e10s broke touch event support, and until we enable APZ touch support (via dom.w3c_touch_events.enabled) it stays broken. In the e10s disable case, however, touch events aren't actually getting delivered to the content, they are getting converted to mouse events. So what e10s actually broke is the conversion of touch inputs to mouse events.
(The good news here is that on touchscreen device, e10s is disabled by default because of the accessibility code, so in theory this shouldn't be a big problem)
just hooking this up someplace where it won't get lost. This impacts Windows touch screen users once they get e10s.

Hey kats, is there a tracking bug for remaining apz + dom.w3c_touch_events.enabled work?
Bug 1244402 is what we're using to track it.
This behaves fine on Nightly if e10s is enabled, because then you get APZ and touch events as well. Inverting dependency, as this needs the touch events to ride the trains before it will be fixed in release.
Whiteboard: steps in comment 2, gfx-noted, aes+ → steps in comment 2, gfx-noted, aes+, tpi:+
Now that touch events are riding the trains I'm going to call this fixed in 52. Note that e10s still needs to be enabled in 52 to get proper touch events support.
