Hello i start my adventure with kde plasma and i wanna make linux look like macOS.

I choose kde plasma because its easy to customize. For distro i choose kde Neon because i thinked will be the best for kda plasma.

I use https://www.youtube.com/watch?v=UYn4UYQ-nTo for my tutorial to customize plasma.

After customize plasma and all look nice but on windows edges are artifacts:

with on blur : all corner problem

with off blur: only top left corner fix

with off blur (down corner) :


When i use other rounded themes this problem exist to.

In tutorial edges look normal and i dont know why i have problem with it.

Anyone knows how i can fix it(i wanna use blur because look nice).
If i change to another distro this will help(if yes what distro is the best for it).

I try fix it by use KDE-Rounded-Corners but this dont help.

Its a bug:
