I looked a bit more at this.

So qTox bug is indeed seems to be related to this. And it might be easier to
reproduce, since it happens all the time, not just on reboot.

To reproduce, you can do the following:

1) Start Wayland session with one screen turned off.
2) Start qTox.
3) Hover mouse over e.g. call button, so that popup notification is displayed
4) qTox crashes instead of showing popup.

After upgrading to Qt 5.14.1 one other Qt application (qTox) sometimes randomly
crashes in QScreen::handle. It might be related to plasmashell crash...

I wonder if it is our bug (we are setting something incorrectly when at least
one monitor is off) or bug on the Qt side.

When using the wayland session, plasma crashes every time I boot. I have a
laptop connected to an external monitor via an HDMI cable. I use only the
external monitor, and have the laptop's display disabled.

My crash log is probably useless because I have no debug symbols, but Thread 1
starts with:  
#6  0x7f07ed45eb62 in QScreen::name() const () from /usr/lib/libQt5Gui.so.5

I'm currently on Qt 5.14.2 and Plasma 5.18.4.1

I think it's the QScreen::handle() function that crashes, i.e. call to
d->platformScreen, not d->platformScren->name().

The code in question is

if (!m_desktopViewforId.contains(m_screenPool->id(screen->name( {

and in QScreen::name() it does

return d->platformScreen->name();

so I suspect for whatever reason it never set a platform screen
