Wrong pixeled shadows around window corners

[lystymoi]

[SOLVED]

With default config shadows are displayed wrong.
They are mostly colored with small transperent fragments.

However when I use greyscale config window borders are normal.

Solution: use glx instead of xrandr as backend.

start picom
picom --backend glx

or

in ~/.config/picom.conf in General settings section comment xrandr and uncomment glx
backend = "glx"
