Bug Description

It appears that pressing the 'preview' or 'settings' button on xscreensaver "interferometry" causes a massive spike in memory usage (>1Gb) followed by a massive system slowdown and eventually a complete hang. (I assume because I'm out of memory).

Attached is a screenshot showing output of Top and system monitor. It shows the initial memory spike. I then tried the "settings" button and things got worse -- so bad, in fact, that top stopped refreshing, so I don't have evidence of that.

I should also say that this is entirely reproducable for me in Unity 3D but does not happen at all in Unity 2D.

Hi! Is this still a problem with up-to-date 12.04?

Yes, it's still happening. I came to see if anyone had a solution for it: apparently not.

I'm seeing exactly the same problem as shadowfirebird when I worked down through the screensavers on 12.04 Precise after upgrading from 11.10 Oneiric.
