Description Waldemar Szostak 2011-01-01 18:07:34 UTC

Version:           2.5.4 (using KDE 4.5.4) 
OS:                Linux

I have two-monitor setup, each with a separate virtual desktop. Both of them have window bars restricted to the current screen and monitor and desktop.

When I have Konsole windows on both desktops and one of the windows is in the full screen mode, the other one won't hide when switching between windows (and it's not set to be 'always on top'). By the window switching I mean using alt-tab or clicking on the window in the window/task bar.

When the first window is maximalised, then the other one switches properly.

The window switching mechanism works as expected (regardless of the window states) also when both Konsole windows are on the same screen.

Reproducible: Always

Steps to Reproduce:
1. Open one konsole in the full-screen mode on one (1) screen.
2. Open another konsole on another (2) screen (also launch any other window).
3. Try to switch to any other window on screen 2.

Actual Results:  
Konsole window (even though it's not maximalised and not in the full-screen mode) will stay on top.

Expected Results:  
It should be possible to switch to any other window.

OS: Linux (x86_64) release 2.6.36-gentoo
Compiler: x86_64-pc-linux-gnu-gcc

This happens to me, same steps. Also dual monitor and gentoo here.
It gets temporarily  fixed by:
$ killall kwin && nohup kwin --replace &
But as long as you click on the full screen konsole that covers a panel, problem reappears.

Comment 3 Thomas Lübking 2012-02-05 23:26:51 UTC

kwin/layers.cpp:526

//         if (minimum_layer.contains((*it)->group())
//                 && minimum_layer[(*it)->group()] == ActiveLayer
//                 && (l == NormalLayer || l == AboveLayer)) {
//             l = minimum_layer[(*it)->group()];

This is however no acceptable patch, but the source of the issue.
This is NOT a dupe of bug #293265

probably dupe of bug #246695
