v2.1.0
Needs Plasma >= 5.27 (5.27.1 to fix issue #87).
This version heavily relies on window decorations, that correctly work with Plasma 5.25 "korner bug" fix.
This effect correctly works with SierraBreezeEnhanced or default Breeze (though Breeze has hardcoded corner radius). You have to make sure, that your radius settings in window decorations match with the settings in LightlyShaders.
