User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:36.0) Gecko/20100101 Firefox/36.0
Build ID: 20141109030205

Steps to reproduce:

1. Firefox made E10S default in nightly
2. I launched firefox as usual


Actual results:

see attached screenshot (all windows fully blank)


Expected results:

Working firefox (which happens if I go into safe mode and manually disable E10S, so there is a functional workaround if people are smart enough to try the safe mode)

I disabled all addons which doesn't help, however creating a new clean profile fixes it.

* My old profile + All Addons + E10S disabled -> works
* My old profile + All Addons + E10S enabled -> blank window
* My old profile + No Addons + E10S enabled -> blank window
* New clean profile + All Addons + E10S enabled -> works

Jonas: do you see that "GLib-CRITICAL: g_slice_set_config: assertion 'sys_page_size == 0' failed" error message when running firefox without e10s?

Yes I see that without e10s (where stuff works) too. The terminal for non-e10s looks similar

Jonas: can you please go into safe mode and then copy/paste your system info from the about:support page (using the "Copy text to clipboard" button on that page) into this bug? This info will help us diagnose whether the problem might be related to known broken addons or a graphics issue.

about:support data when launched in safe mode (with E10S enabled in settings but probably disabled by safe mode in practise):

As I've written previously, disabling all the addons doesn't fix anything so I suppose it's unlikely they are related. However picking a new clean profile does, so it must be some unusual setting I guess.

jonas@datjones#6:

58sz3hxt.otha is the new clean profile where e10s works, ugmfyjon.default-1393063252072 is my many months old profile where it is broken.

My understanding from bug 1098007 is that skia isn't yet ready on Linux (though I might have misunderstood). Jonas, does turning off skia in the broken profile make things work for you?

Yes it does. However, I used skia for months before electrolysis was enabled per default (and it results in a HUGE speed up for canvas operations at least for my own tests on my intel gpu laptop), so I'm a bit confused why the electrolysis tracking was removed - it does seem to be a regression after all.

mrbkap says to use needinfo, so I'll do that. See comment 11.

This probably shouldn't be in Firefox:Untriaged. Is this a duplicate of bug 1098007 or bug 1009722?

On single-process Firefox, we used to use a different compositor that was set up to work with Skia. With e10s, it has to be changed so that Skia works with it. My understanding is that Skia is actually the path forward, so this will eventually be fixed, but the e10s team isn't tracking that work.
