and Plasma's OSD, there's a problem when activating the global keyboard
layout change shortcut. It triggers the OSD and in turn that causes
QEvent::WindowDeactivate and QEvent::WindowActivate events in the app,
leading to text-ui immediately setting the old keyboard layout, making
it look like it's actualy blocking the changes.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">While checking KWindowSystem::activeWindowChanged I noticed that the
active window actually does not change. So I've moved setting the kbd
layout to KWindowSystem::activeWindowChanged slot rather than in the
event() handler. Seems to work perfectly.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I think this is the same bug that is causing the hidden panel to raise
on OSD/notifications and the one that is showing the "plasma" task in
task manager for split second, these two:</p>
