Status: RESOLVED WORKSFORME

Description

See bug 768959 for more information. On my Nexus S there's some black flashing around the spaceship, no shooting ever happens.

I cannot reproduce on my Nexus S, everything seems to be working like on desktop, including the shooting. But you have to wait for 10+ seconds, the shooting only starts once enemies have appeared.

Do you get a fps counter? How fast does it run?

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

I do, but it's only visible when the phone is in landscape orientation. It's too tiny to read and zooming doesn't work. I'd say i'm getting 3 fps but that is not useful info until bug 728524 lands.

Can we check if this is still an issue?

I can't tell. The demo in question appears to immediately fall back to canvas2d on Android, while happily using webgl on my linux machine.

It sniffs the userAgent:

if (!this.nb) this.nb = /(iphone|ipod|ipad|blackberry|palm|symbian|nokia|windows\s+ce|windows\s+phone|iemobile)/i.test(navigator.userAgent);
if (!this.nb) this.nb = !/(windows|linux|os\s+[x9]|solaris|bsd)/i.test(navigator.userAgent);

One of the criteria for trying WebGL is `!this.nb`.
Our Mobile userAgent is `Mozilla/5.0 (Android; Mobile; rv:24.0) Gecko/24.0 Firefox/24.0`.

Well, the info from comment #6 is from http://www.scirra.com/labs/perftest2-webgl .
It might be the same here, though.

Comment 8

[Kelsey Gilbert [:jgilbert]]

It's also unconditionally disabling webgl for Android userAgents:
this.Qi = /android/i.test(navigator.userAgent);
this.nb = this.Si || this.ig || this.Qi;

This WFM, certainly, even with just the canvas fallback (though perf is not great) on my nexus 4. Does it work for all Jeffs?

[Jeff Muizelaar [:jrmuizel]]

Yes. Seems to work but slow.
