Firefox 2020-03-26 11.42 profile.json.gz
4.20 MB, application/x-gzip
Details

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:75.0) Gecko/20100101 Firefox/75.0

Steps to reproduce:

Unfortunately I don't seem to be doing anything specific when the browser freezes. Often, I'm switching tabs to a tab that I haven't used in a while. Sometimes, I'm just clicking a link on the foreground tab that I've been interacting with.

Actual results:

I switched tabs while the foreground tab was loading and the browser hung for several seconds. After it resumed, I captured the Gecko profiler trace I had running (See attached file "Firefox 2020-03-26 11.42 profile.json.gz").

Expected results:

Browser should not generally hang.

For searching:

Gecko profiler reports 3,155ms event processing delay

Apologies if this is a duplicate issue but I couldn't find any related bugs.

Did this start occurring only recently?

Flags: needinfo?(wesley.wiser)

Yes, I've really only noticed this in the last 45 days or so. Prior to that point, Firefox was always very responsive.

Assigning P2 until we gather more information to evaluate the problem.
Looks like we are starting a new process and not receiving anything from it on synchronous Initialize call.
Kats, could this be a problem with process starting or communication infrastructure as opposed to graphics? As far as I see, there is no graphics happening yet, and we are failing to even start talking to that process.

Priority: -- → P2

This is definitely graphics. The stack in comment 1 is for the parent process main thread, which is blocking on compositor init. The compositor thread in the GPU process seems to be stuck in some DXGI lock acquisition. Same as the paint thread in one of the content processes. So looks like a lock contention problem in graphics code. https://perfht.ml/2yl5Vuk

Thanks kats!
Another similar issue was in bug 1556104. It looks like both happen on Windows NVidia (which is a popular combination).
I wouldn't expect locking DXGI to block for too long to the point of hanging. We need someone familiar with this logic to evaluate the danger and complexity. Sotaro, would you be able to evaluate the priority for this one?

Wesley Wiser, can you upload about:support to this bug? Thank you.

Flags: needinfo?(wesley.wiser)

From Attachment 9136030 [details], Compositor thread in GPU process was blocked on SyncObjectD3D11Host::Synchronize(). And PaintThread of content process was blocked on SyncObjectD3D11Client::Synchronize(). Then it seems that D3D seemed to have a problem.

Thank you! We do not change how Direct3D 11 (Advanced Layers) works recently on beta. Then I am not sure which change triggered the problem. There are 3 possibilities that trigger the problem.

  • [1] D2D usage triggers the problem
    • D2D could be disabled by pref gfx.direct2d.disabled=true
  • [2] Direct3D 11 (Advanced Layers) trigger the problem
    • Advanced layer could be disabled by pref layers.mlgpu.enabled=false
  • [3] D3D usage trigger the problem
    • D3D could be disabled by pref layers.acceleration.disabled=true

Wesley Wiser, can you check if "pref gfx.direct2d.disabled=true" address the problem for you?

Flags: needinfo?(wesley.wiser)

I flipped gfx.direct2d.disabled to true 5 days ago and I can't recall seeing stalls like this since then. I will try to pay a bit more attention over the next day or two and verify that is correct.

Thank you!

I can confidently say this fixed the issue for me. This freezing used to happen multiple times an hour and I've watched carefully for it all day and haven't seen Firefox freeze once. Should I leave the preference set going forward or revert it at some point?

Flags: needinfo?(wesley.wiser)

It seems that we need to blocklist the driver for D2D. You could leave the preference set on the PC. Thank you for the confirmation!

Device id range of Nvidia GP107 was from https://pci-ids.ucw.cz/read/PC/10de.

Shouldn't we being using WebRender on this system?

I agree, we should not use WebRender on it. I am going to update the patch.

Sorry, I should've elaborated.

If we use WebRender on this system does the problem go away?
It seems like WebRender should be enabled on this system. The device id should be allowed. I'm confused why WebRender is not enabled.

Here's a few data points that might be useful for answering that question:

  • My device is a laptop (although it is nearly always plugged in).
  • My device is attached to a 4k monitor.
  • My device has both an nVidia GPU and an onboard Intel chip that it switches between for power savings.

Perhaps one of those conditions is preventing WebRender from running?

(In reply to Jeff Muizelaar [:jrmuizel] from comment #21)

Sorry, I misunderstood your comment.

From comment 10, "GPU #1" was "NVIDIA Quadro P1000(0x1cbb)". With it, the PC should be withing DeviceFamily::NvidiaRolloutWebRender. But battery status should be BatteryStatus::None if Firefox is not nightly.

On nightly, battery status does not affect to the Qualified.

Wesley Wiser, can you check if WebRender is enabled on nightly? Thank you!

Thank you, it ways that WebRender is enabled and the PC is qualified for WebRender.

Wesley, can you try running release with gfx.webrender.all=true and check to see whether you still run into this problem?

After resetting gfx.direct2d.disabled back to the default?

Yeah.

Ok, will do. I'll try to report back in a few days.

Enabling WebRender also seems to have fixed the issue for me.
