Catalin, can you please check if other browsers (eg. Chrome, IE, Safari) display this problem on your system?

Comment 2

[Milan Sreckovic [:milan] (needinfo for best results)]

Graphics section of about:support would be most useful.  Also, if you set environment variable MOZ_GL_SPEW to 1 and run again, any additional messages?

I've test this using Chrome and the same issue is reproducible on chrome.(Uncaught RangeError: Invalid array buffer length - error is displayed in Javascript console)
On IE the performance is extremely bad as in 7 FPS.
However on Opera it works just fine.

I've used MOZ_GL_SPEW = 1 as environment variable but the same issue was present.

The bug is reproducible on FF 39, FF 40.0b7 but is not reproducible on the latest FF42 Nightly.

Thanks for the test results Catalin. Based on this I'm not sure we need to worry about this on our end. It looks like things may be fine once 42 makes is way along the trains. We might want to reach out to the developer to let them know but I'm not sure there's something we need to fix on our end.

Any differing opinions?

Actually, just another thought: it might be worth finding a range for when this problem went away in Firefox. If there's something we landed in 42 that makes this go away and it's low enough risk it might be worth nominating it to uplift.

Closing this bug since there were no objections to my earlier comments.
