Comment 16 for bug 1574278

From the following post at the Ubuntu Forums, I conclude that it is a problem of the Lubuntu desktop environment.

Interesting observation. I tried with a current (up to date) Lubuntu 16.04 LTS installed system.

Abiword flickers in a Lubuntu session.

But at the login screen I can also select Openbox (only the window manager, no fancy desktop environment).

Abiword does not flicker in an Openbox session.

The difference is very obvious and repeatable. I need not reboot, only log out, switch session (near the top right corner) and log into the other session.
