I am running Linux Mint 17.1 on a Samsung 365E (np365e5c-s01ub) with AMD Radeon HD 7520G, running Kicad 2015-2-22 BZR 5447, which is all pretty fresh.
I am having these same troubles, and so I am going to try putting the following into /etc/X11/xorg.conf.d/10-fixkicad.conf (which I had to create):
Section "Device" Identifier "radeon1" Driver "radeon" Option "EXAPixmaps" "off" EndSection
thanks to c4757p for this suggestion
