"works for me" patch

I encountered what seems to be a similar problem.  I found that the attached patch works to fix the problems with twinview (or any dual-head system).

Please let me know if I can do anything to help track this down further.

I would have also provided a git:// url, but it appears that the public openbox url is down, and so I could not checkout the code.

I've tried this patch on 3.4.8_rc1, it seemes did nothing, and the bug still there.

if The patch only works on 3.4.7?

here is the screenshoot when the bug appear

thx

Sorry for the misunderstanding.  From reading your first post I thought you and I were perhaps experiencing the same thing.  You can see the problem I am having <a href="http://files.robescriva.com/before.png">here</a>.

I think that the two could be related.  My patch is against the 3.4.7.2 tarball.  I found that the calculation of the position of struts was off by one pixel, and so the windows would not automatically expand into the area it believed the panel occupied.

I'm not an Openbox developer, but would be interested in tracking this bug down as I think it has the same root cause as the bug I wrote a patch for.

See this pic, it's not a one pixel bug, the window after maximized only can expand to 50% of the screen.You can find how to reapear it in this bug url (http://bugzilla.icculus.org/show_bug.cgi?id=3922)

I'm glad if I can make any help to you on fix this bug.thx. :)

What it was in my case is the panel (strut) was extended by one pixel to the right onto the display.  In my previous picture, I showed that it was maximizing to 24 pixels short of the top.

If your dual head setup is such that the bottom panel on the left display were to be positioned at the position 30% from the bottom, it could make the right display act as if there is a strut that takes up 30% of the screen on the right.

You attached your Xorg configs.  Would you look at the resolutions of both monitors and provide me with that?  Also, it might be helpful to know what OS your running so I can recreate your configuration.

My xorg.conf here:

I use gentoo, ~x86, openbox-3.4.8_rc1

Just looking for clarification.  Is the screenshot you attached of your 1024x768 screen or 1280x1024?

oh, 1024x768 screen.
in 1280x1024 screen, I can maximized window full of the screen.
