The Google Maps team is reporting to us that they many reports from users that the WebGL-enabled version of Google Maps, in Firefox 8 and 9, is crashing certain versions of the Intel Direct3D driver on Windows. The interesting thing is that this problem doesn't exist in Firefox >= 10 and in Chrome. It's possible that something in ANGLE changes that makes us not tickle this driver bug anymore. It's possible that this is ANGLE r807. Can I get approval to update mozilla-beta's ANGLE to the same version that is used in mozilla-aurora? That means backporting: changeset: 79001:83d9a9bfa6bd tag: angle4 user: Benoit Jacob <firstname.lastname@example.org> date: Wed Nov 02 00:56:35 2011 -0400 summary: Bug 697333 - Update ANGLE to r809 - no review changeset: 79000:86958303da30 tag: angle3 user: Benoit Jacob <email@example.com> date: Tue Oct 25 08:58:43 2011 -0400 summary: Bug 696889 - Upgrade ANGLE to r802 - no review changeset: 78999:9c15a57d8be1 tag: angle2 user: Ehsan Akhgari <firstname.lastname@example.org> date: Wed Oct 19 10:17:02 2011 -0400 summary: Bug 694801 - VC11 fails to compile angle because pool_allocator<T> doesn't have operator =; r=bjacob changeset: 78998:1f06daff6343 tag: angle1 tag: qbase user: Benoit Jacob <email@example.com> date: Sat Oct 01 00:03:10 2011 -0400 summary: Bug 690735 - upgrade ANGLE to r774 - no review, just syncing with upstream Tryserver push: https://tbpl.mozilla.org/?tree=Try&rev=dc42bce13fd6
[Triage Comment] Approving for beta with the understanding that we can still back this out before building from release if we find any major regressions. We don't normally take such large patches at this point in beta, but given the * user effect * alternative options * (low) record of regression * bake time on FF10 we've decided to take the FF10 ANGLE on FF9 beta.
This is correct, we will be able to back this out if we need to.
Hi guys. Can you advice me how to test this issue? Thanks
On Windows, in about:support, the WebGL Renderer line should mention 809 somewhere in the ANGLE version number. If it mentioned 740 instead, that would mean that the update didn't take place.
I have verified this using the steps from comment6 on: Mozilla/5.0 (Windows NT 6.1; rv:9.0) Gecko/20100101 Firefox/9.0 beta 6 and the issue is fixed: WebGL RendererGoogle Inc. -- ANGLE (NVIDIA GeForce 210) -- OpenGL ES 2.0 (ANGLE 0.0.0.809) Setting resolution to Verified Fixed on Beta.
