The failed screenshot

SUMMARY
Every so often, say, 1 in 3 times, when Spectacle takes a screenshot, it does something odd with compositing and creates massive artifacts over the screen and fails to render parts of windows properly, instead causing odd blur. These artifacts ARE visible when using the rectangle tool, so you can normally see ahead of time, luckily. I have taken two screenshots, one of which was normal, the other of which has the said artifacts.

STEPS TO REPRODUCE
1. Take a screenshot


OBSERVED RESULT

EXPECTED RESULT

Yikes, that's weird. Seems like a kwin or graphics drives issue.
