Description Edward Reiss 2015-05-18 01:00:22 UTC 
KRunner does not start when typing a command or search term (i.e. not using ALT+F2), assuming no window has focus. However, if widget state is changed, i.e. locked to unlocked, or unlocked to locked,  KRunner does start when typing a command or search term unless the user logs on or logs off.

Reproducible: Always

Steps to Reproduce:
1. Click on an empty area of the desktop to ensure no windows are selected
2. Attempt to type command or search term in KRunner

Actual Results:  
1. Click on an empty area of the desktop to ensure no windows are selected
2. KRunner does not appear at the top center of the desktop

Expected Results:  
1. KRunner appears at the top center of the desktop
2. Type a command or search term

Confirmed.

This is regression. I remember implementing this for Plasma 5.
Comment 2 Edward Reiss 2015-05-20 21:02:12 UTC 
Do we know where the issue is?
Comment 3 miku84 2015-05-26 12:38:19 UTC 
Is it planned to be fixed for Plasma 5.3.2?

We really cannot say until we figure out what the problem is. If it's a trivial thing, then it will be backported, otherwise it'll be there for 5.4 (August).
Comment 5 Edward Reiss 2015-05-26 18:07:11 UTC 
Is there a bug ID for Plasma?
Comment 6 miku84 2015-07-17 11:27:02 UTC 
is there any workaround/ patch to have this working?
Or there is absolutely no info about this?

If you toggle lock widgets, it works.

I have tried with locked widgets and it had worked after I enabled the "Show the desktop toolbox" option in the right click desktop menu. But after restart I does not work at all even if I do these steps again. Tried with the default krunner setup as well, without success.
Comment 9 miku84 2015-07-19 17:53:25 UTC 
It is very strange. After restart I need to click to the desktop toolbox (top left corner) and click tweaks and OK, then Krunner works afer typing. 
I think now you should be able to locate the issue in the code.

Problem is here:

desktopview.cpp
    if (!e->modifiers() && activeFocusItem() == contentItem()) {

we're saying if the focussed item is the window then we take the keys
which I think is the case when there's no focussed items.

At some point the main containment gained:

    MouseArea { // unfocus any plasmoid when clicking empty desktop area
        anchors.fill: parent
        onPressed: {
            root.focus = false;
            mouse.accepted = false // Bug 351277
        }
    }

which puts the focus item as the main containment.

I can't find a solution which doesn't just break something else.
