This issue is still present on my laptop though...

Could you at least help me and suggest me a way (ways) how to narrow down the
cause? 
Thanks in advance.

It's highly unlikely that this is a Plasma issue, so I'll close this bugreport
(it's not useful to track this here, just muddies up our bug list and makes it
harder to manage).

Thanks for the report however!

Hmm, I upgraded my linux414 packages back to the latest ones and now it seems
to be working fine...
I am confused.

I will be watching it and if it starts to work again then... would it be
something with the kernel?

I went back to 4.14 and then downgraded this kernel (even 6 updates back) and
the issue is still present.
So it could not be the kernel issue because I am 100% sure this was working
fine before the last update of KDE from Manjaro.

Could you suggest me ways how to isolate the issue?

Based on the issues outlined in those forum thread, this regression coincided
with updating the kernel. Please do some more debugging on the Manjaro forums
to isolate the issue. If indeed it's a kernel regression, the issue should be
reported on https://bugzilla.kernel.org/.

The workaround to wake up the monitor is to start a new terminal (e.g.
Ctrl+Alt+F2) and then back to terminal 1 by pressing Ctrl+Alt+F1.

This issue is super annoying...

Does anybody know how to find such problem in logs?

I enabled KScreen logging but there I don't see anything...

In which log can I see something regarding switching off the screen and waking
up again?
