I am curious if there has been any progress in this issue. I am having a very similar issue on very similar hardware. I have an HP dmz1 4100 laptop with the AMD Fusion E-450 APU. Not only am I having extreme lag in Eeschema, but in Pcbnew as well. Listed are the various system configurations I have tried so far, none which have solved the issue:
Mint Linux 14 Kernel=3.8 Open source drivers
Mint Linux 15 Kernel=3.8 Open source drivers
Mint Linux 15 Kernel=3.12 Open source drivers
Mint Linux 15 Kernel=3.12 Open source drivers+Radeon power management mod+Mesa Stack 10.1
Fedora 20 Kernel=3.11 Open source drivers
Fedora 20 Kernel=3.12 Open source drivers
Fedora 20 Kernel=3.12 Open source drivers+xorg.conf "NoAccel" modification found here: http://comments.gmane.org/gmane.comp.freedesktop.xorg.drivers.ati/20876
Fedora 20 Kernel=3.13rc2 Open source drivers (not stable yet for my system)
Note: On all these varients, I have tried to run KiCAD in Gnome, Cinnamon, and Xfce.
Reasons why I can use the cases where KiCAD ran smoothly:
Case (1): Kernel 3.12 fixes some critical issues I was having with my Broadcom wifi card, but the kernel crashes fglrx.
Case (2): This fix sets the entire system into software rendering. Thus every graphic interface is slow.

(1) Mint Linux 15 Kernel=3.8 ATI Drivers from Ubuntu repos (fglrx)
(2) Fedora Kernel=3.12 Open sournce drivers+xorg.conf "EXAPimaps" modification found here:

Also while looking for a solution, I found this post from 2 years ago: thread. gmane.org/ gmane.comp. freedesktop. xorg.drivers. ati/20105/ focus=20361

So, it might be a Xorg+hardware exclusive issue.... :-/
Here is the print out from "dmesg | grep drm": pastebin. com/aWwmWtEP

Any help will be greately appreciated.
