[16.0.25] Toolbars "truncated"

Sometimes toolbars are displayed incomplete although there's plenty of empty space to the right.

As soon as I click on one of the buttons on the right the toolbars are expanded to the full size.

Maybe this is related to the fact that I regularly switch the Windows VM running TOAD between an external monitor and the internal laptop display.
