I have this file structure and wacther configuration:
The problem is that when I save my scss file the css file is updated in IDE only if I switch focus from IDE window and back again.
P.S.: if I configure scss watcher to compile css files in the same directory where source scss files are located, then css files are uptated right after compilation(as it should).
As suggested in my comment: alter your path in "Output paths to refresh" to point to the actual output file (as in "Arguments" field) and not just folder: i.e. add
/$FileNameWithoutExtension$.css
at the end.
