849038 - crash while stressing pdf.js by scrolling in mozilla::layers::CanvasLayerD3D10::UpdateSurface

Status: RESOLVED WONTFIX

(Firefox :: PDF Viewer, defect, P3)

Description

[Rob North]

This bug was filed from the Socorro interface and is 
report bp-6d18da0d-4ed1-4c61-92ef-64f882130307 .
============================================================= 

Build is: 20.0b3.

Stressed the PDF.js system by opening the following tabs...

http://www.lirmm.fr/~ducour/Publis/phtest.pdf  opened in 2 tabs
http://haskell.cs.yale.edu/wp-content/uploads/2011/02/rt-frp.pdf  opened in 4x tabs.
http://ompldr.org/vZjNrdw  opened in one tab.

Then did a lot of scrolling for a few minutes, switching occasionally between the pdf windows.

The following memory metrics increased dramatically:
    canvas-2d-pixel-bytes
    gfx-d2d-surfacevram
    gfx-d2d-vram-drawtarget
And just before the browser crashed....
    gfx-d2d-vram-drawtarget was at approx 4MB
    gfx-d2d-surfacevram     was reporting -ve memory!!

Is probably related to the bug#842962 which shows high resource consumption, but no crash on scrolling.
Is also related to crasher bug#834256 which with whose signature I saw with
with similar operation is 20.0b2.
See 834256#c19 for a similar of the memory increase pattern.

Forgot to mention:

Repeatability:
   Always, but time taken to generate crash is unpredictable.

Profile status:
   Almost new Mozilla profile. Only used for testing this bug, and bug#834256.

additional hints to repeat:
*Set pdf zoom to 200%, (as was done for the above crash)
*Set pdf zoom to 400%, can even get crashing without scrolling, just by
    quickly switching between tabs.
    Generated the crash: bp-2f8d92bc-073f-4079-9b8d-e84d92130308 in this way.

CPU and memory usage is indeed high but Fx 20 Beta crashes only for me with the second method and it's an OOM: bp-4691e87e-c851-4d2f-bc10-909842130308.

And still present in beta 4 in same form:

See crash: bp-5edd6354-8cde-4ef3-b01e-7b19a2130309 

Prior to beta3, was getting mostly OOM bugs, with no stack trace.
And occasionally the behaviour bug#834256

Was trying to reproduce bug 879320 to get an about:memory report but hit this crash instead. Nightly 24.

FWIW, got this signature when trying https://bugzilla.mozilla.org/attachment.cgi?id=776628
(Bug 894231) with

webgl.force-enabled;true
webgl.prefer-native-gl;true

This is a separate known issue from a few days ago.

Closing because no crash reported since 12 weeks.
