Steps to reproduce:
- enabled gfx.webrender.software and gfx.webrender.all
- scrolled through my facebook news feed
Actual results:
scrolling was slow and felt "laggy" on my Core i5 540m
Profile with "Webrender (Software)": https://share.firefox.dev/2EKrkQW

Expected results:
scrolling should be at least as smooth as the old "Basic" software rendering implementation.

forgot to mention, this happens with the new react-based facebook client which is gradually rolled out currently.

Is performance still an issue here with latest nightly?

Most of the systematic overheads here have been addressed by bugs like 1682194. This is pretty fast now.

Just tested facebook on another machine (dual-core athlon x2 240) and although webrender sofware still feels slower / jerky than "basic" software rendering it is far more useable, also for the case described in this bug report (scrolling in facebook).
