Package: iceweasel
Version: 31.8.0esr-1~deb8u1
Followup-For: Bug #783098

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
	 Scrolling on websites like Stackoverflow and googlemaps leads to 100% Xorg CPU usage as htop indicates: 
	 USER: 'root' CPU: '98%' Command: '/usr/bin/X :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch' 
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
		 Open iceweasel, visiting one of the above websites and scroll on
		 the page spikes the CPU to 100%. Tried the workaround of disable
		 the 'use hardware acceleration when available' option as proposed here:
		 http://unix.stackexchange.com/questions/26234/why-does-stackoverflow-in-iceweasel-cause-high-cpu-usage-for-xorg
		 but no difference. With Chromium CPU usage is less than 10%.
   * What was the outcome of this action?
	 Browser almost unusable for certain pages.
   * What outcome did you expect instead?
	 Amount of CPU usage the machine can handle.
