--text follows this line--
Switching back and forth between workspaces causes the Emacs window to
sometimes rise up and slide underneath the menu bar. Also happens when
switching from higher to lower resolutions (such as when unplugging
laptop from external monitor). The title bar of the Emacs window may
become partially or competely hidden beneath the Mac OS menu bar.

To reproduce, resize Emacs window to maximize or nearly maximize height
on screen, then change workspace back and forth, then click in Emacs
window. Emacs window should then move upwards and slide underneath the
Mac menu bar.

bug#10962: 24.0.95 + extra information

This bug still occurs with 24.0.95 -- this time I built it as a 64-bit application.

I noticed one extra detail necessary to reproduce this. When resizing the window to full height by dragging the lower-right corner of the window, sometimes the bottom of the Emacs window goes a bit below the bottom of the screen. This seems to be necessary to trigger the behavior I noticed previously.

I can reprodude this.  I guess the real bug is that you can resize it below the bottom.  I can't do that if I resize from the bottom of the frame, say in the middle.  The corner has special code to try to redraw the frame contents while resizing.  Not that it works that well.  If we remove the special case, this bug don't happen.  But then we have to replace the redraw-while-resize with something.  I haven't fugured it out yet.  Anyway, this is a regression from emacs 23, I can't resize below the bottom there.

Hello.

I've checked in a fix for this in the emacs-24 branch (bzr branch bzr://bzr.savannah.gnu.org/emacs/emacs-24).  Please try it.

Thanks,

This is expected.  We have to get rid of the whole resize-corner special 
case before this is properly fixed, but that was a too big change for 
24.1.  Try pulling down outside of the corner, at the bottom of the 
window, and you should not get that effect.

Yes.  If there are two or more monitors, we want to be able to resize 
into the other monitor(s).  But we don't know how the monitors are 
related to each other, so we allow resizing outside the current window. 
Unfortunately this is the same thing that allows the faulty behaviour.

This may also go away when the special case for the resize corner is 
removed.
