When using multiple external displays, Illustrator New Document screen and Helpful Hints popups not displaying properly resulting in inability to see and select options necessary to create a new document or see all of the information in the popups and close the popups.

I've called support twice without a resolution. Attempts to resolve have included updating both primary and secondary display drivers.

Work around for creating new is to change Preferences to "Use legacy 'File New' interface", but this doesn't resolve the Helpful Hints popups which can't be closed as a result of this bug.

My specific system configuration file is attached.
