I fixed it by making sure to ignore degenerated matrix. I have no idea for now why this happens. The ZeroDivide is maybe because this is within the UI thread.

what did you fix ? The use of the matrix transform in TRBoxShape or the implementation?
And do you now why the exception "ZeroDivide" does not raise the debugger?
