reduce layer height? what is your actual settings?

I use default settings, it looks like little bit sphere top parts are filled like this.

i’m not sure on an A1 mini, but a 0.4 nozzle can go 0.08 layer height, and 0.3 line width.

Do you think it will solve problem this problem? So this problem is with top surface when it is little bit round

the less layer height, the more line you on low degree surface, it will not “solve” until you go to invisible layer height (like 0.04 with a 0.2 nozzle) but will reduce it

Sometimes using “Concentric” surface for top and bottom layers can help how this looks. I prefer to use Concentric for surfaces, especially if they are rounded.
