This may be the same bug: https://bugzilla.mozilla.org/show_bug.cgi?id=781000

I can't tell for sure because my otoro does not have a working wifi or data connection so I can't use the browser to load websites.  It would be interseting to know if http://djf.net/gl.html renders a green rectangle in the browser on otoro.  And it would be interesting to know if the get.webgl.org cube appears in the task switcher view when you press and hold the Home button.

Confirmed some WebGL not working on Otoro, so blocking. (crystall skull works, cubevid doesn't)

[Andrew Overholt [:overholt]]

Benoit, can you take a look here?

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

The canvas here has width 140px which is not a multiple of 32 so we were running at least into bug 785782, a fix for which just landed and is in the B2G repo

Now retrying with a fresh new build from today...

i meant: bug 782785

Comment 7

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

a build from today just infinitely loops re-booting, so I can't use it to check.

Comment 8

[David Flanagan [:djf]]

I rebuilt this morning and both the phone and get.webgl.org work for me.

Among the webgl-using apps: 

crystalskull works.
cubevid does not (but that could be a video problem instead of webgl)
gallery edit mode works

I think you can close this one.

Yoohoo, this bug is now fixed, so it was fixed by 782785 and so was a dupe of 781000.

My above boot issue was just that I needed the kernel upgrade.

Please give me URLs (maybe even file new bugs) for any WebGL page that still doesn't work. I didn't know about "cubevid").

Comment 11

[David Flanagan [:djf]]

No urls required for those.  They're all apps installed on the phone.

cubevid works fine when run in process. But it is oop by default, so probably isn't running because of https://bugzilla.mozilla.org/show_bug.cgi?id=782460

So not a webgl problem.
