bug#5177: 23.1.90; scrollbar thumb stops working after being dragged

[Ken Brown]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing 
list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

1. Start the Gtk+ build of emacs.
2. Visit a file too big to fit in the window.
3. Drag the (vertical) scrollbar thumb.
4. Scroll through the buffer using the mouse wheel or keystrokes.

The scrollbar thumb stays fixed and no longer shows the relative
position in the buffer.  Clicking in an empty area of the scrollbar
restores the correct behavior.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
     `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/usr/share/emacs/23.1.90/etc/DEBUG.

This does not happen for me.  Must be Cygwin-specific.

Angelo Graziosi told me he has observed similar behavior in Kubuntu. 
Could it be related to the Gtk+ version?  My Cygwin build uses version 
2.18.3.

I can reproduce the bad behavior on Kubuntu 8.04 and 9.10 on which I 
have the builds I did on 20091207.

It would be helpful if a few people who have built emacs on other 
systems could see if they can reproduce this bug.  And if you could 
report which version of Gtk+ you have, that might help narrow the 
problem down.

Thanks.

I can reproduce that on openSUSE 11.1 (with GTK+ 2.14.4 and QtCurve
theme).

On Kubuntu-8.04 GTK+ is 2.12.9 and on Kubuntu-9.10 it is 2.18.3 (as on 
Cygwin). If it is a GTK+ problem, why other GTK+ applications do not 
show that behavior?

...and, it look to me that 23.1 (and the build I did with 
CVS-2009.11.14) work better. But perhaps I am wrong (a sort of illusion :-()

Angelo.

I still see an unexpected behavior: if I move the mouse pointer on the 
scrollbar thumb and click with mouse-1 (only a simple click, tic-tac), 
the thumb stops to follow the scrolling of the buffer I do with mouse 
wheel; if I re-click in the same manner, it works again. For the 
remainder, all works as expected.

Ciao,
Angelo.

Yes, I can confirm that.  (I have to admit I would never have thought to 
just click on the thumb without dragging it!)

Ah, it is a race condition.  I'll have to get back to you on this.
