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?

Exactly. In that case the mclk never changes so there is no flicker. The mclk
has to change

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

This is roughly the same / a little more as with Windows. So we are on a good

Sorry for the delay, I had to figure out which kernel to use, because only
Kernel 5.3.0-rc3 accepts your second patch. Stable 5.2.6 and .7 generate errors

In about 2 hours I will have it built.
