Thank you for clarification, do you think there is a solution for the problem

thank you for the clarification.
Right now I switch manually between low and high when necessary, so I can work
around the glitches.
Do you think it will be possible to achieve feature parity with windows soon?

The patches I posted only affect multiple monitors with identical timing. That
means identical modelines, not just the same resolution and refresh rate. In
practice this generally means you need to use ide

Oh, BTW Martin which type are your 2 identical displays? HDMI (like mine) or
DisplayPort?
I use sound over HDMI, too. And only one display present it.

with 70W i mean total system power-consumption of course.
This is roughly the same / a little more as with Windows. So we are on a good

Hello,
sorry that it took me that long. I was on a historic cycling event in Germany.
Your patch indeed did something.
The power consumption drops sometimes to 70W, but now both screen flicker and
