Will no Compton get rid of flickering or whatever it is?

No. Flickering might be the wrong word. It’s flickering from current image, and showing something in the past or something. You can see gray, and other colors. Rebooting will probably fix it, till it happens again.

Maybe changing the desktop environment will fix it for good.

If it’s the cable, why would rebooting fix it? To lazy to unplug and plug back in.

What might fix it, is ctrl alt backspace. Then I just have to relogin.

After clicking a shortcut on accident in Chrome, the flickering started. Don’t know what keys I clicked.
