Crashes when trying to move a window in expo mode

[Michael Kogan]

I get a crash and the following output when trying to move a window in expo mode:

---------------
/usr/include/c++/11.1.0/bits/stl_vector.h:1045: std::vector<_Tp, _Alloc>::reference std::vector<_Tp, _Alloc>::operator[](std::vector<_Tp, _Alloc>::size_type) [with _Tp = float; _Alloc = std::allocator<float>; std::vector<_Tp, _Alloc>::reference = float&; std::vector<_Tp, _Alloc>::size_type = long unsigned int]: Assertion '__n < this->size()' failed.
Abgebrochen (Speicherabzug geschrieben)

Grabbing the window is fine, but then moving the cursor triggers the crash.

Using Compiz 9.14.1 installed via https://aur.archlinux.org/packages/compiz-easy-patch/ If some of the patches used by the package are suspicious, I can retest with an unpatched Compiz, please let me know!
