'Display errors in MySQL Workbench

MySQL Workbench is displaying a series of boxes instead of characters in the results screen, and a number of elements are disappearing from the window when a query is run.

I'm receiving a number of GTK out of memory errors in the syslog when this happens too:

drawing failure for widget 'gtkmm__GtkPaned': out of memory

I've recently upgraded to Ubuntu 20.04, and installed MySQL Workbench via snap.

How do I fix this?

Before executing query:

After executing query:

Solution 1:[1]

In my case, it happened on the first time running mysql-workbench after install.

I stop and then restart mysql-workbench, everything is OK.
