2 windows of equal height.

Yes, from last emacs -Q, even outside Org Export, you need two windows
and M-x fit-window-to-buffer RET will fail sometimes.  But I can't
provide a reproducible case for now.

What happens is that, when `window--resizable-p' is called with the
pixelwise parameter set to `t' (from within `window-resize'), then
the delta (as pixel height) is too high and `window--resizable-p'
returns nil -- and window-resize an error.

This is *only* when I use the fullscreen mode from my window manager.

When I use toggle-frame-fullscreen, the pixel height is different.

See this short screencast demonstrating the bug:

PS: Notice that M-x toggle-frame-fullscreen RET is "less" fullscreen
than with the internal command of my window manager.
