Created attachment 136151 [details] Example of Kate with toolbar padding resulting in strange look Breeze adds more padding around toolbars now. Which at least on my low DPI small laptop screen makes things look a bit odd. While also turning more vertical & horizontal space into dead spaces, which for element-rich UIs comes at noticeable cost. * emphasizes mismatch of heights of toolbars and tabbars * emphasizes mismatch of active areas of menubars and toolbars * seems out-of-scale for bars in dock widgets, where usually smaller icons are used * adds to misalignment of toolbar buttons at begin/end with other UI elements If Kate & KDevelop UIs are not yet in your set of apps to check changes of Breeze against, please do add them :) See Kate screenshot attached with markup of where things are experienced as regressions (while already not that perfect before). Perhaps we need a Breeze variant for small-screen :)
Kate overrides lots of contents margins to be 0; I'm not really sure if this can be considered a Breeze bug if Kate's 0 margins clash with a style's non-0 margins. If an application overrides margins to be 0, they're going to look cramped compared to a style having noticeable margins.
