[Bug 416567] Re: Taskbar module often does not show window in the list

 

This bug is really tricky!

OK, maybe i have a little bit hint about this.
I think this starts to happen when cairo-dock has been running for several hours.
I usually keep my system always on nearly 24/7. so that maybe a reason i notice this bug more.

I caught a screenshot of the bug . [this was in a session of ~12hrs]

Notice: From the switcher widget and the screenshot, there are 4 windows
open 1.Firefox 2.Evolution 3.Xchat and the fourth one is the recent one
Calculator

But note the module only shows 3 windows , the *calculator is missing from the windows list* .
Even the Switcher widget does not show the calculator.
[Unfortunately i had forgotten to start cairo-dock in debug mode]

I wondered if this was a calculator specific bug , so i first closed
calculator and i restarted cairo-dock in debug mode and again opened
calculator. but this time the calculator is shown in the list.

>From my previous experience it was not specific to any app and i now
believe it is related to running cairo-dock for long hours.

May not even be related to Taskbar module as such since the switcher
widget is also affected.

I'll get back with a debug log about this.
Thanx

Bug description:
Binary package hint: cairo-dock

Using the latest version 2.0.9 from > https://edge.launchpad.net/~cairo-dock-team/+archive/ppa

When a new window opens , sometimes , it does not show up in the taskbar and skips the list of the open windows.

This is very confusing when several windows are open and I only realize that the window is already open when i try to open the app again and it comes up from behind !
While i'v checked if it is a problem with the window skipping the panel window list too , but alas, its a problem *only* with cairo dock.
This is not specific to any app or any event , it is very random and I'm not sure how to debug this issue.

This is not a new problem , I'v been facing this problem since version 1

Workaround:
Restart cairo-dock > now the app is shown in the list of open windows.
