I confirm, on my 1680 pixels wide the top line is on one line and if i reduce the width of the window to less, it spread on 2 lines hidding the scale menu. It's already the same if I reduce the resolution of screen on the PC to 1440 pix. Then it is impossible to have the window of gc-project wider and the menu is always partially hidden. Probably to solve taking into consideration the width of window and the fact that the top line have to be reduced for smaller width like it is done in Ms-Office by exemple (only an icon in place of a full field with text when the width is smaller)
