My crystal ball says youʼre using a HiDpi display, and you have menus
enabled. Setting the environment variable GDK_SCALE to 1 before
running emacs might help.

There have been some scaling related fixes in the just-released
emacs-26, would it be possible for you to try that version?

Regards

Robert
