Description Vishnu 2019-01-13 16:02:11 UTC

I just began using the wayland session, and when I do login (auto-login), one of the windows open (along with my usual auto-starts) is one that reads: "Compositor (System Settings Module)".

This happens on every login.

X session management still runs as before.

Please confirm 

system settings -> startup and shutdown -> desktop session -> on login

is set to "start with an empty session"

Comment 2 Andrius Štikonas 2019-01-14 21:30:26 UTC

Happens independently of that setting. I reproduced it even with start with an empty session.

Comment 3 Vishnu 2019-01-15 15:25:08 UTC

Yes, the desktop session is set to 'start with an empty session' on login.

Comment 4 Christoph Feck 2019-02-08 14:42:33 UTC

This is from KWin, automatically showing the dialog when it is sure the settings are not right and need to be adjusted by the user.

Please add the output of the following Konsole command when this happens:
qdbus org.kde.KWin /KWin supportInformation

I can't find any code that spawns the Compositing KCM. Does KWin actually do that?

it did, but IIRC I removed it.

Coincidentally, I haven't managed to reproduce this yet after upgrading to Plasma 5.15 beta. Although, even before it wasn't easy to reproduce due to kwin crashes when display outputs are changed.
