Distribution/OS:  Fedora    |  Bug Status:  Unconfirmed
----------------------------+--------------------------------
 I was doing something in write and noticed that it resulted in my fans
 spinning up all the way and heating up my leg.   This is especially
 noticeable when running 2 instances and using collaboration.

 You can see the top of the abiword canvas flickering through grey as well.
 After going into the Gtk+ inspector and ticking the box to show redraws,
 the whole canvas was flashing red (redraw) multiple times a seccond.

 I couldn't see it on the abiword GNOME app, but I'm pretty sure I've seen
 it there before.  Maybe they patched it in their app but we haven't?

 Fedora rawhide 24 with abiword-3.0.1-4.fc23.x86_64.  There's a new release
 coming up at the end of this month, so I better check then.
