BTW, this is interesting.  Because DRI_PRIME=1 is only for 3D rendering,
basically it doesn't matter which output is.  The only difference is the window
size of glmatrix.  More memory usage, more chance for crash, as it seems.
You can try to lower the display resolution via xrandr, say, 1024x768 on the DP
monitor, and run glmatrix there.  This may reduce the crash probability, if my
guess is correct.

Also, before testing any newer versions: you can test rather the old one that
worked before.  Namely, install openSUSE 13.2 kernel on top of Leap system.
Install it like
  rpm -ivh kernel-default.rpm --nodeps --oldpackage
then it should be still bootable.  Confirm that this doesn't lead to any crash.
 If this works stably, it's really a kernel regression.
