Hi all I came across this combination in https://tracker.freecadweb.org/view.php?id=4351
export QT_SCALE_FACTOR=1 export QT_AUTO_SCREEN_SCALE_FACTOR=0 Applying those two variables makes the debian packaged FreeCAD work just fine. I tried QT_SCALE_FACTOR in a scattergun fashion between 0.1 and 2.0. Anything less than 1.0 caused garbled menus, anything higher than 1 makes it work just fine, but the menu texts get huge. Here is a QT pointer to the same problem: https://forum.qt.io/topic/110033/qmenu-and-qt_scale_factor
