When using canvas tag, moving a layer containing big svg content (for example 15000*15000, actual for browser games with big maps) rendering seems laggy and slow only on Windows platform (linux moves smoothly and fine). NVIDIA videocard, Linux openSuSE distro, windows version WinXP, sp3.

Reproducible: Always

1.Create not too big canvas on html
2.Put big div with SVG on it
3.javascript to move div containing svg
Actual Results:  
laggy on windows, smoothly on linux

Expected Results:  
smoothly everywhere

could you please hook up a testcase using "Add an attachment"?

Comment 2

[Yury]

Testcase is in 590662.

1. Go to http://sontan.name/uploads/projects/far7/ff/game.html
2. On left click activates an animation
3. On dblclick creates some large images

I don't know whether this is an issue with SVG or layers.

Comment 4

[Karl Tomlinson (:karlt)]

Oh, this is 1.9.2, so the issue existed before layers.

Bug 590662 comment 2 says there's a performance regression on trunk.

Comment 5

Yes, it's SVG bug.

http://sontan.name/uploads/projects/far7/ff/game_svg.html

double click creates SVG with randomly rotated images, right-click on star or planet creates "selection" - circle filled with gradient (pure-svg).

In WinXP animation turns into slideshhow.

Is this still a problem in Nightly builds, or even in FF11? It seems to work fine for me.

Comment 7

[Robert Longson [:longsonr]]

Seems fine to me on Windows.

[Jonathan Watt [:jwatt]]

Okay, lets mark it as worksforme now then, unless someone else is still seeing problems.
