Bad performance on running tsvg
_static talos test
https://treeherder.mozilla.org/perf.html#/graphs?series=autoland,1646684,1,1&series=autoland,1683650,1,1&series=autoland,1651392,1,1&series=autoland,1686495,1,1 tsvg_static performance is worse with WR enabled on both Linux and Windows. Marking P1 for windows regression.
We can't release this to the field, but we can let this ride to beta. However, we want to investigate and understand the bad perf numbers asap.
Priority: P1 → P2
Whiteboard: [gfx-noted] → [gfx-noted][needs-investigation]
The perf difference here is pretty small on Linux/Mac. The gearflowers.svg subtest is regressed, since with non-WR we do parallel OMTP painting in tiles, and with WR we paint the blob image in a single thread. On Windows the difference is much larger, and it looks to be entirely because we're now drawing SVG in software, where we previously got Direct2D accelerated drawing for it.
Matt, do you think we still need to block here? Are things better enough now that we can ship?
No, tiled blob images made the scores almost identical.
