The animation in "tag cloud" on the right causes scrolling to be really slow.

This profile seems to be in a .bin format? What kind of profiler were you using with the attached profile? Thanks!

From the profiles, I see super long 500+ms times to do XRender::Sync, _XSEND and XUnlockDisplay. I know we're planning to reduce our dependence on XRender, which should help this test case.
Depends on: 1241832

It's still slow, I can grab another profile (although bug 1241832 caused bug 1247935, so I don't know if it'll stick).

This is now fixed (both with gfx.xrender.enabled set to true or false), I wonder if this was fixed by the same fix for bug 1247935.

That makes sense, yes. As Mason noted, a lot of the profile was spent in XSync waiting for stuff to be drawn. So if there was somehow contention for the connection to the X display, the changes I made in bug 1247935 would massively reduce that contention, since it no longer uses the XSync mechanism at all.
