[Message part 1 (text/plain, inline)]

Here is 100% reproducible test case: run

emacs -q -mm -l test.el

with the attached test.el, and notice that the mouse pointer
is banished to the middle of the frame.

Afterwards manually executing `M-x toggle-frame-maximized RET' twice
fixes the frame dimensions.

This happens in GNU Emacs 25.0.50.1 (x86_64-linux-gnu, GTK+ Version 2.24.23)

Noticed.  Good catch.

Obviously these values can't be right: 170 * 6 gives 1020, more than 300
pixels off from 1366.  What happened is that you requested a change of
the font size for a maximized frame.  In this case I no more allow
changing the size of the frame (since otherwise you'd have lost the
maximized state).  Now the pixel sizes of the frame remained unaltered
and I decided to quit adjust_frame_size early _without_ recording the
new numbers of lines and columns of the frame.  Damn me ...

Hopefully fixed in revision b53b1ca..233dcf1 on trunk/master.  Please
check.

Many thanks for the recipe, martin

Thank you, I checked that now everything is right!
