Hi,

I can reproduce this bug with a simple qxembed frame. Steps:


(1) Get qxembed-emacs:

https://bitbucket.org/ArneBab/kembed-emacs/src/71b958b3f737a62987dfc7cd39eb3edcb02308b2/qxembed-emacs.py
    hg clone https://bitbucket.org/ArneBab/kembed-emacs

(2) run ./qxembed-emacs.py

(3) resize the qxembed-window.

(4) do the same with ./qxembed-emacs.py --basic
    this opens emacs with -Q --basic-display


For me, (3) has an embedded emacs which shrinks down instantly to maybe
5 chars after releasing the window.

With (4) the embedded emacs is adjusted to the window size after the
first resize and then stays embedded correctly. But it looks odd due to
the --basic-display.

Best wishes,
Arne
