I noticed this when updating my system. The Muon Discover layout shows nearly all the items bunched together, improperly spaced out. Doesn't look polished at all. Reproducible: Always Actual Results: Particularly when updating, layout has improper spacing between items: buttons are cut off, and other items are improperly proportioned. Update text is overlapping the progress bar. Expected Results: Layout should be neat, properly spaced, with no overlapping. Bug discovered while using Kubuntu 15.10 x64, KDE Plasma 5.5.4 via Kubuntu backports ppa.
