Screen Flickers on YY but not on XX

[mparillo]

I dual-boot YY and XX, and both are up-to-date. But my YY flickers, and XX does not. I saw this:

This is probably a totally wrong comment, but I just installed KDE Neon on bare metal on my about two year old 6 processor AMD.

As a test, I am using the "Dashboard" menu setting.

I got "tearing" with the provided Open GL 2.0

I got a "jitter" on the "whole" of the "Dashboard" using open GL 3.1

Using Xrender things are stable.

The "jitter" sounds kind of like your.... jitter / whatever in calc, probably NOT, but just thought I'd report what happened with me.

and I wondered if that might apply, but why, unless something changed between YY and XX (yes, lots has changed, but you know what I mean).
