Created attachment 116008 [details] demonstration See the screencast please. SOFTWARE VERSIONS Arch Linux KDE Plasma Version: 5.14.2 KDE Frameworks Version: 5.51 Qt Version: 5.12 beta3
Does this reproduce when using a 1x or 2x scale factor?
Reproducible with 1x and 1.2x scale factors.
I can confirm this issue. It's in qqc2-controls-style and I can't see where it's coming from. :/
This is a regression in Qt 5.12 beta :( Will have to fix Qt I guess.
Works for me now on Qt 5.12 git, so hopefully it's been fixed.
