osd: Fix a crash when quitting from QML signal handler
kscreen_osd_service[9979]:
Object 0x55a9840ff5c0 destroyed while one of its QML signal handlers is in
progress.
Most likely the object was deleted synchronously (use
QObject::deleteLater() instead), or the application is running a nested event
loop.
This behavior is NOT supported!
qrc:/qml/OsdSelector.qml:102: function() { [native code] }
Call to quit() should be posted to an event loop to avoid destroying Osd
objects with their engines while a key press signal handler is still
running. Additional clean up must be performed to ensure that a map
does not contain dangling references, ans thus double call to hideOsd()
won't cause another crash either.
Also, don't bother hiding individual OSD instances if we are about to
quit anyway. That's what other code path with timer is [not] doing
already.

https://bugs.kde.org/show_bug.cgi?id=459368 --- Comment #14 from Iyán Méndez Veiga --- This issue can be "minimized" if I turn off the laptop, plugged it to the docking station and turn it on already attached. And it is "maximized" with hot plugging. I also noticed that if the laptop is suspended and I attach it to the docking station, it is not "aware" that the lid is off and the screen remains on, while with Plasma 5.25, laptop would resume with the screen off and only show in the external one(s). -- You are receiving this mail because: You are watching all bug changes.

--- Comment #11 from Vlad Zahorodnii ---
At quick glance, it looks like kscreen osd crashes in
osd/osd.cpp
35:connect(output.data(), ::Output::destroyed, this,
::hideOsd);
i.e.
if (m_osdActionSelector) {
m_osdActionSelector->setVisible(false);
}
