This would indicate that the toolbar lines implied resize is the culprit
but this

is very strange.

I had this when toggling menu bar lines on Motif builds.

Please try (if those work on your system) with

- frame-resize-pixelwise t initially

- a pgtk build using GTK2

- a normal "non-pgtk" GTK3 build

and also do initialize

frame_size_history = list1 (make_fixnum (100));

and post the contents of the file displayed by

   (frame--size-history)
   (pop-to-buffer "*frame-size-history*"))
