Created attachment 122487 [details] Cut off highlight+hover effect at 3x scaling This screenshot uses a modified version of Breeze (https://cgit.kde.org/breeze.git/log/?h=ndavis/highlight). The lack of antialiasing on the hover effect outline is a separate issue that seems to only happen in Dolphin.
