Since Plasma 5.8.0 tray icons are small, too small. I'm fixing it by reverting previous line in: org.kde.plasma.private.systemtray/contents/ui/main.qml to: property int itemSize: Math.min(Math.min(width, height), units.iconSizes.medium) Reproducible: Always

I also have this problem, the solution SeeLook provided works and resolves the issue.
Judging by the attached screenshots, this should be resolved when bug 360333 is resolved. Maybe close it as duplicate?
