Spun off from bug 332413 comment 9. The filter in the following file makes the UI hang for ~3 second any time I try to scroll (remove the filter and it's fine): http://upload.wikimedia.org/wikipedia/commons/c/ca/Video_Standards.svg
Flags: wanted1.9+
This would benefit enormously from both bug 416305 and bug 418201. (Restricting filter processing to the dirty rect would greatly speed up the shadows for the really large objects that are mostly offscreen.)
Depends on: 416305, 418201
BTW there's this strange line in the input: <feComposite in2="shadow" in="SourceGraphic" operator="arithmatic"></feComposite> "arithmatic" is misspelled so we do a regular composite. Not sure what the author was trying to achieve there.
Always crash there: http://upload.wikimedia.org/wikipedia/commons/c/ca/Video_Standards.svg
Flags: blocking1.9?
Andriy: what platform? I don't crash there on Mac trunk.
No crash here either Mac or Linux.

Attached image small related(?) test case (obsolete) —
extremely small test case with very similar symptoms
Video standards is slow because it uses filters. The small related test case does not and is therefore not this bug.
I have a tree with fixes for bugs 416305 and 418201 and they totally nail this page.
Another slow SVG file, this time without gradients. http://www.w3.org/DesignIssues/diagrams/arch/follow.svg
techtonik, there are 2 gradients: <linearGradient x1="0" x2="1" id="Gradient" gradientUnits="userSpaceOnUse"> <stop offset="0" stop-color="#d9edff"/> <stop offset="1" stop-color="#91a9c5"/> </linearGradient> <linearGradient id="Obj_Gradient" xl:href="#Gradient" gradientTransform="translate(1e3 71.639908) rotate(90) scale(59.999992)"/> <linearGradient id="Obj_Gradient_2" xl:href="#Gradient" gradientTransform="translate(1e3 234.14001) rotate(90) scale(60)"/>
Removed these lines gradients, but the scrolling is still sluggish. I can't say if it is faster than before, but it is still very slow for sure.
My patches help with that page too.
So what are the plans on integrating these into the trunk?
Attachment #321437 - Attachment is obsolete: true
The relevant patches have landed on trunk. This should be much, much faster now. I'll take the liberty of marking this fixed.
