When comparing view definitions from local objects to latest source control version (perforce in our case), SQL Source control doesn't properly read the data compression options from the source control version. So we'll get a difference, showing "WITH (DATA_COMPRESSION = PAGE)" highlighted orange on the left....however the source control file also has this clause, it's just not being read properly. If I check in the file, it will refresh and the same object will still show a difference with source control, even though it's not.
