How to fix Oracle SQL Developer IDE typing is super slow

None the less there is one bug that returns every now and then, and it doesn’t seem to be version specific. This is the super slow editing or typing in the IDE SQL code windows, this in fact, in some cases prevent and interfering with our work. How to solve this irritating issue?
