How do I stop the watersplash on screen

When any NPC from the raidable bases hits me or even swings at me and misses it adds this water effect similuar to blood effect on my screen that's stopping me from seeing nearly at all, anyway to remove this effect ?

hi, I don't know what you're referring to :p

Uhh I'm not sure best way to share a screenshot, I hope Imgur works since I don't know how else to explain.

It's the watergun effect but I get it from them even shooting/missing, melee attacks  and anything the NPCs can do to attack, results in watergun, for everyone on my server at least.
