[tex-k] Question about MetaFont online display

I would like to report a possible bug in MetaFont.
I have setup a test environment to reproduce it:
git clone git://github.com/igor-liferenko/mf && cd mf
In the output you will see redundant calls to blankrectangle and updatescreen:
This is METAFONT, Version 2.7182818 (TeX Live 2017) (preloaded base=mf)
Except these duplicate calls being useless, they may also cause undesirable
small initial blinking effect in an online display driver.
Anyway, these duplicate calls are strange and cause a question for
what they are needed.
Does anybody have an opinion on this?
