WindowMaker hangs when turning on TitleBar for application #13

Open MarioNigrovic opened 3 years ago

MarioNigrovic commented 3 years ago

I use WindowMaker on my work desktop, because I really like the look and feel. Recently, I've been having to use an application which tries to do its own window management and it disables the titlebar, titlebar icons and the resize bar. In the past I've been able to iconify applications like these and then right-click on the icon to access window attributes and add the titlebar back, etc. However, with this application when I do this, wmaker just locks up and sits and spins 100% on a CPU. I would really like to be able to force decorations on to this window so I can shade/unshade it to declutter the screen (it's unfriendly about popping up/down, too). What should I do to help diagnose this problem? Or is this just a lost cause?

Could you provide steps to reproduce this issue?

MarioNigrovic commented 3 years ago

It's pretty straighforward:

  1. Start the application (icvwb from Synopsys if that helps)
  2. Iconify it (Alt-M in my setup)
  3. Right click on icon to bring up Attributes form
  4. Un-click on "Disable titlebar" to re-enable it
  5. Click on "Apply"

Immediately upon clicking Apply, WindowMaker freezes and starts burning 100% CPU.

I just discovered that if I kill the --for-real process, I can recover the session, and I used SIGABRT to get some sense of what it had been doing:

(gdb) backtrace

0 0x0000000000410d01 in wArrangeIcons ()

1 0x000000000041295e in paint_app_icon ()

6 0x00000000004432b2 in real_main ()

7 0x00000000004426a4 in main ()

I also discovered that I had a fair number of these "stuck" wmaker processes hanging around on my system, because they weren't dying when I killed of previous Xvnc's that were hosting them. I can attach the core file and binary if that would help?

MarioNigrovic commented 3 years ago

Oh, I did discover that when I manually add NoTitlebar = No; to my WMWindowAttributes, there's no problem.

gryf commented 3 years ago

Perhaps attaching core file could help, if you still think, that this is a problem. If you think that solution you discovered is good enough, than you can close the issue.

I don't think he should close the issue. It's a bug.

MarioNigrovic commented 3 years ago

Here are both the core and the executable, in case having the latter helps with interpreting the core. I don't know if our IT department builds the version we run, or if they find a copy somewhere and just install it. core.127721.gz wmaker.gz

MarioNigrovic commented 3 years ago

Oh, BTW, I mentioned that there's a workaround mostly to clarify that it's not necessarily the interaction with the particular application that is the problem, but perhaps it's something about changing the titlebar setting.

That icvwb is a proprietary software, where can we get a trial version? or do you have any other example of app that have the same issue. I tried to reproduce the issue with a gtk3 home made app but wmaker is working properly.

MarioNigrovic commented 1 year ago

Folks -

It happens to me quite frequently with just ordinary xterms. Simply drag a window that starts partially hidden by another.
