Firefox 36.0 Smooth Scrolling Lagging

[MickZA]

Anyone else have a problem with smooth scrolling on Firefox 36.0 on systems other than Fedora, I've been forced to switch smooth scrolling off in preferences because it lags for a second or two and then jumps to catch up - very irritating. Doesn't happen on all sites but very noticeable in the MyBB forums.

My installed version:

firefox.x86_64 - 36.0-1.fc21

I dont have that issue on my system (manjaro linux 3.19)

Switched between KDE, XFCE, and Compiz, and no probs here.

Seems it might be a "bleeding edge" issue with 36.0.1.

Centos 7 is still on 35 and Ubuntu on 36.0, smooth scrolling is fine on both.

From the Firefox 36.0.1 release notes:

CSSOM-View scroll behavior implemented allowing smooth scrolling of content without custom libraries

I have 36.0.1 installed and no lag on 4 different machines.

Might be Gnome3 related also but it's only cropped up with 36.0.1.

Firefox 36.0.3 update released for Fedora 21 - smooth scrolling issue has vanished.

I noticed two things.

1) HTML 5 video (or maybe Adobe flash video) is causing lag.
2) and Adobe Flash seems to crash a lot lately and the plug-in stops working. (might be related).
