1813318 - Video with filters applied stutters while playing (appears to be throttling)

Status: NEW

(Core :: Graphics: WebRender, defect)

Description

[Mayank Bansal]

Go to https://codepen.io/rodzyk/pen/poZoYmO
Toggle the "Toggle Sharpen" button
Play the video

ER: Stuttery video, without any increase in CPU or GPU. This may mean that there is some throttling going on. If you move the mouse between the boundary of the video and the demo pane, the stuttering reduces.

Profile with first half without filters, and the second half with filter applied : https://share.firefox.dev/3Dmw7Uc
Profile with media preset: https://share.firefox.dev/3wAhrNc

Im filing in Graphics, but this may be fission related.

I can reproduce the issue on Windows10.

Regression window of significant drop in frame rate (Although there is some frame drop even with good builds.):

Seems like the fix for this is to render SVG filters in webrender (bug 1409486)
