Created attachment 151528 [details] Screenshot STEPS TO REPRODUCE 1. Go to system settings → Appearance → Application style 2. Click on the configure button for Breeze OBSERVED RESULT The two comboboxes on the first tab are too narrow. Or rather, they are narrower than is possible, because there is whitespace to the right. EXPECTED RESULT Use all available space that is there, just as the controls on the other tabs of the dialog.
