[Fluxbox-users] confusing bug of unable to siwtch to / show new windows

Hello. The problem, which I believe is a bug, is hard to describe but keep
coming back to me in the last a few years, recently with Ubuntu 11.10
happens much more frequently than before.

A newly opened window, be it an application (e.g. Firefox) or an fluxbox
tool (e.g. fbrun), would show on the iconbar but does not draw itself. You
can click it on the iconbar, but it wouldn't show up neither. The window, if
having focus (you can identify that by the color of it in iconbar), can
accept input. say I can keep typing in fbrun to launch a new program, but I
wouldn't see fbrun itself.

When this happens to a window, all newly opened window after it would stop
showing up too. Older windows are not affected. Thus, when it happens I
usually logout and login again.

It's extremely difficult to determine which application in my .xsession is
related to such a behavior, thanks to the difficulty to reliably reproduce
it. e.g. Once I removed xcompmgr from .xsession and this problem stop to
happen, thus I thought they are related, until a month later this bug happen
without xcompmgr again. It would take a season (3 month) to figure out the
relationship between the exact .xsession item and the bug, if there is such
a relationship.

So where should I look for for solving this issue? Thanks.

Best.

No idea - but I have the same issue, happening most often to Firefox. I
managed to see the windows again, after right-mouse-click in taskbar and
iconofy, maximise, unmaximise and so on - and then they re-appeared
(sometimes) .

I don't use xcompmgr, and I *think* it happens more often under ubuntu
oneiric then under natty.

Any ideas how to fix this permanently?

Cheers,

Rainer

yeah: make it reproducible so we can spot the bug in the code.

Difficult! You never know when it happens, besides, when it happens, you
cannot open thunderbird to check what command to use to diagnose. I had
to write the command with pencil on the screen to capture it..

check this bug report:
http://sourceforge.net/tracker/?func=detail&aid=3191824&group_id=35398&atid=413960
that may be the same issue...

Unlikely - I usually do not minimize firefox, and I tried to reproduce it
with the bug report, but it is working as expected (OK - not switching to
firefox, but the file / directory is opened) and I can un-minimizze it
(firefox 8.0)

Hi,

sometimes this happens to me too. It seems that windows are drawn, at
least in my case, but they are outside the screen.
I have a hotkeys to place the window in center/left/right/top/bottom
and just use them to get the window back on screen.

regards,
Maxim

Can you find the window in "xwininfo -root -all" when it's theoretically
onscreen, and see if the display coordinates are offscreen or something?

(note that window manager frames and toolbar icons are included in the list
- it's likely to be embedded in a window manager frame, and probably a
"normal" size, rather than something like 10 pixels wide).
