Remove unused refresh arguments from invalidation

After recent refactoring the refresh window arguments are not used in
many invalidation functions. This fixes the code and removes unused
arguments to avoid future confusions.

Was just about to fix this myself :) Great that I don't have to.

It was confusing me, so I decided to bring it outside my current work. I might need to do another refactoring change, so it is good to have it as a basis.
