OK, thanks for the reply. Also the text editor windows for editing table or column comment, default expression, condition for check constraint, etc. in table editor (opened by the button with three dots) has the same issue.
BTW, congrats on what seems to be a successful beta release. I am thrilled about the dark mode (and I am sure that many other users will be), and also the possibility to make a connection read-only will prove useful.
Thanks to the developers and keep up the good work.
