Created attachment 114075 [details] window not dogged I have HiDPI display, scale factor 2, use PLASMA_USE_QT_SCALING=1. I have set visibility Dodge Windows. With my settings dodging is not working halfway under dock. I have to move window more than half under dock to hide. I assume it has some relation to scaling factor.
same issue you must remove PLASMA_USE_QT_SCALING=1 as mentioned at: https://bugs.kde.org/show_bug.cgi?id=396678
