CentOS 7 in a VM running KDE has been stable for web and email and a
few big Java applications.   Scientific Linux beta 7 running natively has
frequent
X server crashes both for the console and Xvnc.  It is using the ATI radeon
driver (VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
RV730 GL [FirePro V5700])

[    23.397] (II) Loading /usr/lib64/xorg/modules/drivers/ati_drv.so

I have not seen (EE) lines - in the case of Xvnc the server stops working
and has to killed
manually.

I'm very short of time at present, but I would start by checking for
reports on RH bugzilla,
I would also consider installing the vendor's drivers.
