1087827 - [Azure] JavaScript canvas performance is very bad with hardware acceleration ON

Status: NEW

(Core :: Graphics, defect)

Description

[Geoffrey D.]

User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0
Build ID: 20141011015303

Steps to reproduce:

1. Go to http://soulwire.github.io/sketch.js/examples/particles.html
2. Move your mouse and notice it is running very slow
3. Start Firefox in safe mode and repeat
4. Notice it is now fluid


Actual results:

There is a difference of performance between normal mode and safe mode, which shouldn't happen.

This has also been tested on a new (blank) profile and on a different computer.
Chrome behaves properly.


Expected results:

No difference (or at least a smaller one) between normal mode and safe mode.

Disabling hardware acceleration (setting gfx.direct2d.disabled to true in about:config) seems to "solve" the problem.

Seems that hardware acceleration is plying up here.

[Wayne Mery (:wsmwk)]

Still see this in a current nightly build?

Comment 6

[Alice0775 White]

I can still reproduce the slowness with enabled HWA in Nightly41.0a1 non-e10s.

Comment 7

[Geoffrey D.]

Seems to work for me in 41.0a2 (2015-07-05) e10s and non-e10s.

Might need confirmation on this.

Comment 8

[Alice0775 White]

I can still reproduce the super slowness with enabled HWA in Aurora41.0a2 & Nightly42.0a1 non-e10s/e10s.

Comment 9

[Imran]

Issue still exists for me on Aurora 41.0b4 when hardware acceleration is on.

Comment 10

Setting gfx.canvas.azure.backends = skia,cairo fixes the slowness
