I have a short panel on the right. In order to seperate the menu button, starter etc. from each other I placed spacer items between them. Spacers are set to flexible size. I set the panel to have a minimum and a maximum size (look at the screenshot). The problem: After starting plasma the panel is set to the maximum size not the mimimum. When I unlock the widgets the panel magically shrinks. Locking it again will set the panel to its (IMHO) correct minimum size. Reproducible: Always
Created attachment 76955 [details] screenshots of the panel before/after unlocking
Plasma 4 has been unsupported for several years. If you can reproduce this in Plasma 5, please file a new bug. Thanks!
