@franz I faced screen flicker on 5.4.40 upwards in kubuntu. Now on Mx Linux 5.10 no issues.
@oros a totally different perspective! Thanks for your input. Is this on an Intel chip by any chance?
@franz Yeap! You guessed correctly. I5 10210u. I've been following some bug tracking reported issues. It has not been fully resolved. Some regression issue I think. The flickering happens on the external connected via dP screen from a laptop and caused some FIFO A B issues.
@kmicu I'm using the Intel driver (i915). I haven't tried anything yet. It really isn't that bad.
