Weird things happening on dashboard

This seems to have just happened recently.
(It has to be recent as I have only made these flows recently.)

Attached are two pictures.

NR 0.19.4
Dashboard (recently updated) 2.14.0

Normally the screen is good, but now and then part of the GUI goes away.
I don't think I need to say which part.

If/when it happens, if I refresh the page, it is ok.

Code for the whole page below.
