Artifacts on glass, white pixels

Hi, I wanted to make window texture and I stucked with glass material…
Even If I make glass material only with GLASS BSDF -> (mat. output)SURFACE it is the same like on this screenshot.

Thanks for help

I think I found solution but ONLY for ‘daytime’ texture - I have had ‘LIGHT’ ‘installed’ behind the window - but I can see that this problem Is more visible when light inside the building is heading on floor (check out screenshots). There still is problem with ‘night time’ texture If I would like to make this texture only with light inside the ‘building’

This happens when light is heading to floor

I’ve deactivated this light and texture looks fine :D.

and when light inside the building is heading to window these ‘artifacts’ are less visible than on the firt screenshot.
