I try selecting a Place entry in Dolphin only for the mouse cursor to freeze on the resize icon, preventing me from doing anything else but resize (this also happens with FreeCAD). My current and only solution is moving the mouse like a maniac and right-clicking until it disappears.
I originally thought a system update broke the mouse functions, since everything worked until said update. It’s been about 2-3weeks since, plus another update, and the issue persists.
