Thanks for the bug report. This particular bug has already been reported, but feel free to report any other bugs you find.

The full-screen applications that are minimized makes desktop freeze. I tried it with LibreOffice Calc, same effect. All full-screen applications cause this problem.

Could you open a new bug if you have a similar issue? this is a memory corruption one, so please open a new one. Thanks.

I was using LabVIEW and compiz just crashed when I tried to closed one of the open windows.

My package manager (synaptic) just ended installing some packages. Firefox was maximized, but currently hidden. I have to press OK button on synaptic dialog showing end of install process and everything freezed for a while, then compiz restarted

I experienced this same bug but my video driver is i915

[James Peters (reteptj73-)]

It occurred when I shut Firefox down then tried to open it up afterwards.

Same issue here. Just a few seconds after logon while emptying trash.
Don't think of memory corruption - have other distros running well on this machine.

This bug doesn't mean that the physical memory is corrupted. It just means that Compiz allocated some memory and had a pointer to it, but when he tried to release this memory, pointer pointed to region of memory that is invalid or has already been freed (not allocated anymore). It's clearly a bug.
