I confirm that the problem is caused by the nvidia 270.41.06 drivers (and not primairly by konsole).
I can reproduce it with kvirc and gimp by just resizing (or maximizing) them.

The symptom is a hangup of the entire system or "pixelated" corruption of the screen (see the
attached screenshot). 

In the syslog the following messages can be found:

[ 1623.494466] NVRM: Xid (0000:01:00): 13, 0001 00000000 00005097 000015e0 00000000 00000100
[ 1637.600063] NVRM: Xid (0000:01:00): 8, Channel 00000001
[ 1639.600033] NVRM: os_schedule: Attempted to yield the CPU while in atomic or interrupt context

Disabling desktop effects does not fix the problem for me.

The 173 legacy nvidia driver is not affected by this issue (though it
has different problems that make it unusable).
