First let me confess that I only have dangerous smattering in this topic.
Would it be possible before cloop image creation to identify
files/blocks/ranges that are unchanged compared to the previous image? If so
could these ranges be mapped to the same blocks during compression?

This is almost an academic example for an automatic (unit) test! :-)
You can write a test that automatically "clicks" on the switcher and triggers
the bug. Then you fix the bug and run the test again. Now the test must pass.
Now whenever you change something you run this test again. This way you
ensure that this bug will never ever rise its ugly head again. To ensure
software quality you actually have to write tests for every bug you get
reported. The nice thing is that running some hundred tests automatically can
be done by the developer with a single mouse click. This is even much faster,
more reliable and not so tedious and boring as manual tests during a beta
release. Anybody else enthusiastic about automatic testing now? ;-)
