6713 2006-01-22 03:32:30 -0800 resizing SVG with blur filter is incredibly slow 2014-05-12 05:54:35 -0700 1 1 1 Unclassified WebKit SVG 420+ Mac OS X 10.4 RESOLVED FIXED http://jan.kollhof.net/projects/svg/examples/aqua.svg InRadar, NeedsReduction, SVGHitList P2 Normal --- 7207 68469 26389 1 eric webkit-unassigned emacemac7 ian jeffschiller joost krit oldest_to_newest 29331 0 eric 2006-01-22 03:32:30 -0800 Resizing Safari window sends CoreImage off the deep end http://jan.kollhof.net/projects/svg/examples/aqua.svg We need to reduce this to the minimal crashing SVG. At which point we can either fix it in WebKit, or I can take that knowledge to the CoreImage team. 30205 1 eric 2006-01-26 16:20:17 -0800 This is a reproducible crasher for SVG. Adding to the SVGHitList. 30219 2 eric 2006-01-26 16:42:07 -0800 Also now in Radar: <rdar://problem/4423939> Resizing Safari window sends Core Image off the deep end 30503 3 eric 2006-01-29 06:23:48 -0800 The situation is much better now. I discovered as part of fixing http://bugzilla.opendarwin.org/show_bug.cgi?id=6849 that every time we requested a filter object, we were adding it's filter elements onto the filter stack. This caused us to quickly build a filter stack larger than core image could handle. The performance is still poor, but much better. 30932 4 gblock 2006-02-01 02:16:20 -0800 ... is it just me, or are some effects being added on each time I resize this? Nightly from the 31st... Is that related to this? 31340 5 joost 2006-02-04 10:50:30 -0800 Performance for resizing this is hellish, but it works and it's consistent it seems.... 32240 6 a 2006-02-12 10:00:22 -0800 as altha points out, while horribly slow this is no longer a hang. renaming to reflect this, decreasing priority, and removing from hitlist. 32450 7 a 2006-02-14 01:48:07 -0800 making hitlist again, we are too slow to ship 40585 8 7995 darwin 2006-04-27 02:33:08 -0700 Created attachment 7995 Slightly reduced testcase It appears the Gaussian blur effect is causing a dramatic slow down. Slight butchering/reduction of the SVG while still exhibiting the behaviour. Removed buttons, text and gradient effects, leaving enough gaussian blurred objects. 87564 9 gsherloc 2008-08-01 06:20:42 -0700 I see a little CPU usage when resizing the window when visiting: http://jan.kollhof.net/projects/svg/examples/aqua.svg but no performance problems.
