Happening at least on OSX 10.13.4, todays nightly (62.0a1 (2018-06-21) (64-bit)) Confirmed to be webrender only (doesn't happen when I disabled gfx.webrender.all) Steps: 1. Load http://jlongster.com:8080/s/bigsvg/ 2. Scroll down the page 3. Once you get near the bottom (where the bubbles start to fan/thin out), scrolling appears to drop frames/jank Profile captured at: https://perfht.ml/2Kansq3 Kats suggested this may be fixed by bug 1455422

Also this didn't seem to be a problem for me on my external monitor (24" 1080p), but it is very noticeable on my 13" retina display. I thought it may be related to high dpi, but changing the system display scaling didn't seem to help.

Seems about the same, as of 63.0a1 (2018-08-13) (64-bit), still stutters when scrolling down

I cannot quite reproduce aforementioned jank on the test page but I've just encountered something that fits the description at https://www.bbc.co.uk/radio: all SVGs move "strange" during scroll: mostly faster than rest of page (on sub-pages slower), some even in wrong direction (presumably due transforms). But jumps to proper place after scrolling finishes. Behold the amusing showcase: https://imgur.com/a/s6IhvtO

This still doesn't seem ideal. There are still invalidations during scrolling (can be seen with gfx.webrender.blob.paint-flashing
).
