Description Maciej Mrozowski 2010-01-26 05:51:07 UTC

Version:            (using Devel)
Compiler:          gcc (Gentoo 4.3.4 p1.0, pie-10.1.5) 4.3.4 
OS:                Linux
Installed from:    Compiled sources

This is KDE SC 4.4 RC2 using Qt-4.6.1

Steps to reproduce:
1. Ensure applications are not minimized (no idea how it's related to anything but that's important!)
2. Activate shortcut for "Show Dashboard" to show dashboard (Ctrl+F12 by default, META+D in my case - this Windows key is handy)
3. Now activate it again to get back (do not use "Hide dashboard" menu entry!).
4. plasma-desktop task is shown in task manager on panel (it's not actually ghost task as it disappears when dashboard is closed)

Now, it seems that "Show dashboard" action has been implemented literally as "show" - so it's not toggle switch any more (it used to work like I expect). I think it's this way because it really looks like dashboard was being created again as:
- activating it for the 1st time shows dashboard (as expected)
- activating it again brings desktop back and it's immediately followed by dashboard being shown again (with ugly flickering in the process).

More notes:
- I'm using TwinView on NVidia GFX5200, nvidia-drivers-173.14.22 - driver works very well here
- OpenGL compositing enabled
- typical plasma desktop with Desktop activity on both screens
- plasma widgets: 2xfolderview, dictionary, file watcher, analog clock (causing mentioned little flickering?), notes, weatherforecast

Still reproducible with 4.4.1. This time this ghost task appears in task manager on panel even when 'Hide dashboard' cashew menu entry or 'Widget Dashboard' (X) is pressed.
