icon problem, eg. "paintbrush"

icon “paintbrush” when dragging, quadruples in size, making it impossible to use, this also happens with other draggable formatting icons. I have not found any indication of why this has happened.

This also happens with the Clone icon for formatting in Calc. Cannot find any way to stop this which I believe something to do with Context menus /buttons.

No operating system nor LO version given, please see Getting started
