There's at least two different stacks under this signature. The above is the more recent one and seems to have started with buildid 20200709093347, it's a NULL pointer dereference from the looks of it.

The second one is the following:

The first one uses Fission and Has dual GPUs.

I have found this comment:
(Rares Doghi from bug 1625857 comment 14)

The only issue I noticed was the following error in the Failure log displayed multiple times on Nightly, im not sure what it means : GP+[GFX1-]: Present1 failed: 0x887a0001

In Release 74 there is this error displayed (GP+[GFX1-]: Updating unknown shared surface: 60129544279) as well as this one (CP+[GFX1-]: Failed to connect WebRenderBridgeChild) for scrolling really fast on reddit .

This issue started to occur as soon as I upgraded the driver version to the one from the reporter.

Sotaro - do you have any suggestions?

The second has this crash reason:
bp-291dc982-eb6e-4a5c-a7a5-b4e840200713

MOZ_CRASH Reason (Sanitized) MOZ_DIAGNOSTIC_ASSERT(false) (egl->fStreamConsumerGLTextureExternalAttribsNV( egl->Display(), mStream, nullptr))

GraphicsCriticalError of the second had "Context has been lost". It meant that context of ANGLE was lost. It seemed to happen by Texture2D allocation failure within ANGLE.

App note of the crash report does not have "EGL? EGL+ GL Context? GL Context+ ". From it, EGL seems not used when the crash happened. Then it seemed that ANGLE with WebRender was not used. ANGLE could be disabled on WebRender by pref "gfx.webrender.force-angle=false". And there should be a STR that hit RenderDXGITextureHostOGL::EnsureLockable() without ANGLE WebRender.

I do not know the STR of the crash. But I found that RenderDXGITextureHostOGL is created with flash video. Though I did not see RenderDXGITextureHostOGL::EnsureLockable() calling.

Bug 1577336 added the D3D11TextureData creation. It is still valid even when ANGLE with WebRender was disabled.

All recent crashes had SwComposite thread. Then it seems to related to software WebRender.

I could reproduce the crash with software WebRender on Windows.
