Artifacts with comrpess textures (basis)

Hi! I am trying to add support for compressed textures in my game. And faced artifacts with semi transparent images that uses blend mode. I am using PIXI v7.1.1, for compressed textures I choose format basis and  compressed png to basis with basisu -uastc -uastc_level 3 -uastc_rdo_l .75. How to fix artifacts?
