Im having trouble with pixel depth offset on UDS plugin

Hi guys, i have an issue with pixel depth offset, ive installed Ultra dynamic sky on to fresh project and the snow is not working correctly, is anyone have an idea what could cause this problem? This plugin should be working straight away and it does for everyone except me, i didnt change any .ini files in the game engine settings etc, and my graphics card is amd radeon. I am a beginner, i attach screenshots of what i mean.
