Description D1mon 2021-09-02 07:42:31 UTC 
The compositor does not turn on when the system starts (Compositor -> Enable compositor on startup -> On). It happens itself turns off after some time (possibly after turning off the monitor)

I fix the error:
Compositor -> Rendering backend change "OpenGL 3.1" to "OpenGL 2.0" or "Xrender" and back to "OpenGL 3.1".

how can i change "Rendering backend" from console (qdbus)?

Today the composer turned on after starting the system. But after turning off the monitor (6 min), the composer turned off (stopped working). "Energy Saving -> Switch off after 6 min".

I try all three: Xrender, OpenGL 2, OpenGL 3.1. All works some time and then turning off compositing.

The problem was in: "Allow application to block compositing"
