2022 MBA M1 8/256 freezes temporarily with external monitor

[Daud]

LG HDR 4K Display 32UP83A-W
2022 MBA M1 8/256
connected by the supplied USB-C cable, mirroring to the LG display

Trying out the monitor, going with 2560 x 1440 resolution as it looks better for my eyes than the 4k where everything is so tiny.
In general good experience but during the use, at times the MBA gets stuck for like 10sec. Can't move the side bars in Firefox, change to Settings, like there is a held in the process inside. Them suddenly it works again.

AM I ASKING TOO MUCH FROM THE MBA ?

That sounds odd. I used a M1 MacBook Air with a 4K display for almost 2 years and never saw anything like that.

Is it always Firefox? I don’t really ever use any browser except Safari. I would switch between 2560x1440 and 1920x1080 because it was a 24” display but I used it in scaled 25600x1440 more often than 2x native 1920x1080.

this "sounds" like memory are being swapped, this pause happens to me too when osx is swapping mem and all my windows takes a long pause. keep an eye on your activity monitor.

I used Firefox. Will try Safari and watch Activity monitor (for what?)

watch out for ram pressure. green is ok, yellow is caution, red is indication that you need more ram.
