Firefox 30 & WebGL problem.

In order not to hijack other threads.

Firefox 30 doesn't work with WebGL on my system. R600 FOSS drivers. Nothing custom on the system. Everything from the offical repos.

webg.disable is set to false in  about:config.

Re: Firefox 30 & WebGL problem.

It is probably mesa (r600) related since in my VM it works fine.

Re: Firefox 30 & WebGL problem.

Are there any other people with a similar setup to mine (r600 GPU) experiencing this??

Re: Firefox 30 & WebGL problem.

Todays update in mesa didn't fix this. Could there be that there is a missing build flag (in the official package) or whatever?

Re: Firefox 30 & WebGL problem.

I don't know if this is connected, but I might have the same problem. On twit.tv, they use the sublime video player and when in fullscreen, the video is choppy as f*** (or whatever that is called in english, the german word for it is: "ruckeln"). After reinstalling several old packages I isolated firefox 30 as the root of the problem. On ff29, it is working as expected without video lags or anything, but with ff 30, fullscreen fullhd videos are totally unwatchable.

Nah probably not. Check your gstreamer stuff. They changed it in FF30. (uses gst 1.x now).

Re: Firefox 30 & WebGL problem.

As far as I can tell WebGL is working normally in FF30 with a r600 card (6850, Barts like yours). I tested with a few of the 'experiments' at Google:

Re: Firefox 30 & WebGL problem.

Exactly the same setup (6850) and it doesn't work. And i am confused because i don't mess with the system at all. The last thing i touched was the group/passwd files because of .pacnew files but that probably has nothing to do with it.

In case it helps.

Re: Firefox 30 & WebGL problem.

If i set webgl.forse-enable to true it works. (it was working fine without it previously) So is this an issue with the latest firefox?? Chromium had the same behavior when i tested it (wasn't displaying webgl).

And as it seems there is a pretty good reason its disabled. It crashes quite often in ie. Chrome experiments.
