752472 - Investigate why hardware acceleration doesn't work on legacy hardware, when it does on IE10 and Chrome

Status: RESOLVED INCOMPLETE

(Core :: Graphics, defect)

Description

[...]

User Agent: Mozilla/5.0 (Windows NT 6.2; rv:15.0) Gecko/15.0 Firefox/15.0a1
Build ID: 20120506030520

Steps to reproduce:

With a ATI Radeon X300 you can't enable hardware acceleration in Firefox unless you specifically change the layers preferences. Upon restart the browser just crashes immediately.
In IE10 accelerated graphics is enabled by default.
In Chrome when changing preferences hardware acceleration works without problems or crashes.

Firefox gets 3 on psychedelic test without HW, fails to even open with HW on.
Chrome gets 3 without and 1111 with (and it it doesn't crash with HW on)
IE10 just flickers with HW forced off but still has a score of 9 and with HW a score of 703.

I really like Firefox, is there a reason why these browsers can still accelerate graphics on legacy hardware whereas Firefox can't?

Does this still not work on Windows 8 RTM and the latest Firefox 16 beta?

Resolved per whiteboard
PS: Firefox is still a lot behind other browsers in hwa area, but as nobody from developers care about that...
