Description Luca Carlon 2019-06-29 07:10:00 UTC

I was used to develop in the past (probably last year) running a docker Neon image into a Xephyr window. Now I can't do this anymore as nothing is displayed in Xephyr except the mouse pointer.

STEPS TO REPRODUCE
Simply run the two commands reported here: https://github.com/KDE/docker-neon.
1. Xephyr -screen 1024x768 :1 &
2. docker run -v /tmp/.X11-unix:/tmp/.X11-unix kdeneon/plasma:unstable

OBSERVED RESULT
Xephyr only shows black with the mouse pointer inside (which is different from the one of the host).

EXPECTED RESULT
I should see the Plasma desktop.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Kubuntu 19.04
KDE Plasma Version: 5.16.1
KDE Frameworks Version: 5.59.0
Qt Version: 5.12.2

ADDITIONAL INFORMATION
I attached logs docker is printing to stdour/stderr. I see many errors, so it is difficult to understand for me which are relevant.

This seems to be a problem that appeared in KWin in the last 6 months or so.  The desktop runs fine but as soon as your run KWin the window contents are just black.  There are window borders which show.
