Hi 

I encountered a problem when I compiled the latest master (Using Ubuntu
16.04 and the corresponding GTK version)


I attach a screenshot 
The config options are 
auto-apt run ./configure --prefix=/opt/emacs29  --without-pop --with-mailutils



I bisected the problem and found out that the culprit is 
 commit 74c07733698b95eb455edcafab8634a700a3194f
  Author: Po Lu <luangruo@yahoo.com>

  * src/emacsgtkfixed.c (XSetWMSizeHints): Improve fix for bug#8919.

Thanks.  What happens if you set frame-resize-pixelwise to t in
early-init.el?

I have never used early-init.el

For debugging I always use emacs -Q

So do you want be to have early-init.el in my home directory or in emacs/src?

How should I start emacs then?

In your home directory.

Without "emacs -Q", if the bug can be reproduced that way.

Thanks.

Ok, interesting:
first the screenshots of emacs -Q and emacs -q

Then the screenshot with the early-init

It seems to look ok but when it finishes loading all my init files, it
looks like emacs -Q

Sigh.  If you instrument emacsgtkfixed.c as follows:

	  if (hints->width_inc && data[5] % hints->width_inc)
	    data[5] += (hints->width_inc - (data[5] % hints->width_inc));
	  if (hints->height_inc && data[6] % hints->height_inc)
	    data[6] += (hints->height_inc - (data[6] % hints->height_inc));
         (Add instrumentation following this line)
	  fprintf (stderr, "XSetWMSizeHints: %l %l width_inc: %l height_inc: %l\n",
		   data[5], data[6], hints->width_inc, hints->height_inc)

what is printed when you start Emacs with "-Q", and Kwin shrinks your
window?

I don't know anything about that C code (and the last time, I did some C coding is some 10 years ago)


Not sure I understand, I apply the patch attached below and run make again:

Then I get an error (so most likely I misunderstood you)

That's odd.  Unfortunately the previous code resulted in menu bar size
hints set by GTK not being respected, so I'm at odds wrt what to do
here.  On one hand, your window manager is clearly buggy, but it used to
work.  I guess a user option to enable the previous behavior would be
the most reasonable course of action.

Does anyone else have an opinion here?

Two comments:

    1. The compiling error I mentioned is not important?

    2. Since I use athena, and this you fixed, for me that fix is not
       urgent, besides I have to admit that I should upgrade Ubuntu.

No, it's a warning, and the data printed is correct.

I compiled it finally a ; was missing.

The message is 

./emacs -Q
