Status: RESOLVED WORKSFORME

(Core :: Graphics: CanvasWebGL, defect)

Description

[Martin Stránský [:stransky] (ni? me)]

I tried some WebGl examples (http://learningwebgl.com/blog/?p=859 for instance) and when firefox quits it crashes in MOZ_gdk_display_close().

I run Fedora 12 / ATI Catalyst driver (ati-driver-installer-10-4-x86.x86_64)

Comment 1

[Benoit Jacob [:bjacob] (mostly away)]

I tried this page and quitted firefox, and didn't get a crash. Tried with both a debug build, and a release build. I have Fedora 13 / x86-64.

The biggest difference between our setups is that I am using the nvidia proprietary driver. Together with your backtrace pointing to a location deep into fglrx_dri.so, this suggests that you hit a fglrx bug.

Hopefully proprietary drivers will soon be a thing of the past! It's certainly taking this route at least on the ATI side. Once the patches in bug 571831 are checked in, our WebGL implementation will (in principle) run on free drivers.

It may be related to Bug 576933.

[Joe Drew (not getting mail)]

Martin, does this still happen since bug 576933 was fixed? I'm going to opportunistically mark worksforme, but please reopen if that's not the case.
