The largest of those was a single allocation of 62000 bytes. There were several more of these calls, with smaller sizes, and varying in the nesting depth of single_menu_item and friends.

Can you show the backtrace from the 62000-byte allocation?

Anyway, I think this is a separate issue, unrelated to the one that is
the subject of this bug report.

Agreed. Nothing about this is specific to remote frames or slow connections. Should I open a new ticket, or follow up on emacs-devel?

I'm still seeing no display problems with the test branch; I'm fine with closing out this ticket now.
