There is at least one bug in that version having to do with the
automatic querying of the terminal's background color introduced
with patch 7.4.757.  There have been two subsequent patches that
have fixed all known issues with that feature, 7.4.766 and 7.4.770.

Updating to version 7.4.770 or later should fix the problem.

Regards,
Gary
