I just did a brand new install of manjaro i3 in a dell precision 5540 and I’m getting kind of a flicker on the screen.
By flicker I mean that when I do an action the screen switches between the last and actual states a couple of times for a bit more than a second after finally “stabilizing” on the final state.
It’s also curious that it’s not on every action, but more like a intermittent thing that happens a couple of time per minute (so enough to be very annoying).
Some examples where it is more visible:
When I switch a tab in the chrome browser, it keeps going back and forward between the last tab and the one that I switched to.
When typing (in any app) some letters/words that I just types disappear and appear again a couple of times. Sometimes it even stays “stuck” in the last state (so the word is there, but doesn’t appear on the screen) and I need to do some other action to see the word on the screen.

About the swap, didn’t knew that there were advantages on having it when there is a lot of RAM available and no intention to user hibernation, thanks for that!
I tested in that order and it just got stable at 5.4. Thanks!
BTW, now there is some “tearing” when I’m using some specific apps (I noticed it in “manjaro settings manager” and “simple screen recorder”) that wasn’t happening before.
Curiously, I tried to record it with simple screen recorder but it doesn’t appear on the video.
