1195763 - Hang on startup when running Actual Multiple Monitors application

Status: RESOLVED INCOMPLETE

(Core :: Graphics, defect)

Description

[zoltan.rajnai]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.155 Safari/537.36

Steps to reproduce:

Updated Firefox from 39.0.3 to 40.0.2 (I also tried with 40.0 and get the same results)


Actual results:

Firefox failed to start up a second time.

If I change the following line in pref.js it starts up :
user_pref("extensions.lastAppVersion", "40.0.2");
Firefox shows no window, but I can see the process in Process Explorer.

This is the top of the callstack for the Main Thread:
xul.dll!ID2D1RenderTarget::CreateSolidColorBrush(const _D3DCOLORVALUE & color={...}, ID2D1SolidColorBrush * * solidColorBrush=0x00000000)  Line 3314	C++
xul.dll!mozilla::gfx:rawTargetD2D1::Init(const mozilla::gfx::IntSizeTyped<mozilla::gfx::UnknownUnits> & aSize=, mozilla::gfx::SurfaceFormat aFormat=)  Line 937	C++
xul.dll!mozilla:references::GetBool(const char * aPref=0x00000000, bool * aResult=0x00000000)  Line 1374 + 0x29 bytes	C++
xul.dll!RecordingPrefChanged(const char * aPrefName=0x0fe99512, void * aClosure=0x6d612e50)  Line 423 + 0x13 bytes	C++


Expected results:

Firefox should start up every time, without having to modify prefs.js

Thanks Rahimul

Just a bit more info:
Cleaning FF, and creating a new profile didn't help.
I even had to manually edit profiles.ini to achieve this because the Profile Manager wouldn't even start.

I think I found the culprit:
I am running an application called Actual Multiple Monitors (v5.1.1).
If I exit that application Firefox starts up every time.
The question is what changed between 39.0.3 and 40.0.2 that would cause this?

Are you using multiple monitors?? why do you need that application anyway.??

Comment 9

[zoltan.rajnai]

Yes. I'm using it. Unfortunately (for me) the latest version of Actual Multiple Monitors (8.5.1) does seem to work, but I have no license for it.
It replaces the system task bar with one that works on multiple monitors.

zoltan, could you please follow these instructions to get a hang report of what Firefox is doing? The stack you've provided doesn't make a lot of sense, and I expect that it's broken in some way.

You may want to try switching from a 32-bit Firefox build to a 64-bit build and see if that helps. Some tools that inject DLLs into Firefox will change behavior when you switch architectures.
