Breeze Widget sytle is very boxy and takes too much space to accomodate small amount of text. Plasma 5.1 introduced Breeze widget style which makes KMail now take at least 50% more space to accomodate the same number of lines that Oxygen was accomodating. I have 30 enteries in KMail's folder window which were fully accomodated at 22x22 in Oxygen widget style without any scrollbar. With Breeze even at 16x16 7-8 folder lines are hidden and with 22x22 11 folder names are hidden which have to be regularly accessed by scrolling down. Reproducible: Always Steps to Reproduce: 1. Use Breeze widget style in Plasma 5. 2. 3. Actual Results: Breeze style makes same information occupy more space Expected Results: Space should be proportionally applied.
The breeze design is developed as a community effort which happens in the "Visual Design Group" forum on forum.kde.org. Feel free to participate there. Concerning this bug report I'm sorry to say that this is a WONTFIX. Currently this is the *intended* design and the perspective of a design is always subjective. It's totally fine that you don't like the design as it's obviously not possible to have a design which suits all users. Luckily you can switch the design and switch to e.g. Oxygen.
I like the design very much but it's taking way too much space compared to Oxygen while showing the same amount of information making scrollbars to kick in all 4 directions. If you want to make things clean by spacing them out that would also mean you have to get rid of some UI elements. Otherwise you are scrolling with all your 10 fingers. I was told to file a bug report so I did. I will talk to VDG too. Thanks Martin.
