Expected The value is updated. More details: When I use another window manager such as openBox, metacity, xfwm, etc. It works as expected. When I launch kwin with: KWIN_COMPOSE=X kwin --replace & It works too. It works as expected with windows and mac too. I've same issue with Centos 7 and kwin 4.11.19.

*I update the value in the JLabel which is inside the JFrame
ps2 : you can resize the windows to force the redraw and see the new value.
how does it look like in another compositor. All the WMs you mention are non composited.
Martin Flöser : What do you mean about compositor ? 3D compositor ? It works with gnome-shell and unity. If you have another example, I can test.
No problem with compton too.
This issue report is quite old. Can you please confirm, that it still persists with KDE 5.23?
