Fog of War Bugs out, please help

So, in recent games i noticed that the fow is clearly bugging out. The issue is that after sometime of playing a specific area on the map gets the bug and it doesnt show the fog of war, but instead just hides the champs and minions in a space where its shown to be visible to me(but still no fog of war), so they just pop out of nowhere and it got me killed a couple times and its really confusing when youre playing. Fix this please its starting to get annoying, or if anyone has some suggestions im all ears? Cheers.
