Flashing pool to the east end of Dry Fang

there's a pool in Dry Fang Canyon that flashes from blue to brown rapidly. it's located at the top of a mountainous area to the east of the canyon.

I was playing on a community server called Nat Hist. I was searching around Dry Fang Canyon for water when I saw a large pool in the distance. I noticed it was flashing rapidly from blue to brown. at first I thought it was something to do with the terrain loading up as I approached the area. as I got closer though, i soon realised it was a full on glitch with the water texture itself. this brings me great concern as it could end up triggering an epileptic fit if someone with epilepsy were to come across it while playing the game.

if the glitch wasn't present, I'd expect this body of water to be either blue if it hasn't been drank from, or brown if it has been drank from frequently. it should not flash rapidly from blue to brown.
