@Dorabella123 If you want to make the effect disappear temporarily, just remove the snow cover. Bring up the cheats console (cmd-shift-C) and enter "testingcheatsenabled true" without quotes. Then shift-click on the ground and select Seasons > Snow Depth > None. You can always cheat it back later.
@Dorabella123 That's a good point; I've been wondering why it took so long for people to report this issue. But maybe it's more common to play with the camera facing away from the road and towards the back of the lot, and some worlds don't have that many roads. And of course many people play with advanced rendering off.
