832116 - very slow HTML5 demos

Status: NEW

(Core :: Graphics: Canvas2D, defect)

Description

[Konstantin Svist]

Some HTML5 demos from http://fff.cmiscm.com are very slow

Specifically, these two:
http://fff.cmiscm.com/#!/section/wipertypo
http://fff.cmiscm.com/#!/section/universe

On Chromium 23, both demos show up with reasonably smooth animation

No changes..

Up to Firefox 24 now -- choppy animation, no improvement at all. 2nd demo does not render correctly
Chromium 27 - smooth animation, both demos look great. 1st demo uses 100% CPU, 2nd demo doesn't

Slow for me in trunk, fine in Chromium.
I'm guessing this is canvas2d, though there's a change it's just DOM.

a chance*

Comment 7

Fedora 20, 3.15.10-201.fc20.x86_64
Firefox 32 (tested with default software mode & with OMTC hardware acceleration): choppy animation, very low frame rate
Chrome 37.0.2062.120 (default software & forced hardware override): smooth animation, no issues

Note: my hardware is different from when bug was originally opened, now using
00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06)

note, OMTC works quite well with this machine, so I'm using it most of the time
