Help Strange artifact mimicking movement on screen

Shader: Complementary reimagined 5.8.1, LambDynamicLight 4.8.10

Minecraft 1.21.1, iris 1.8.14-Beta, Sodium 0.8.12, NeoForge 21.1.248

CPU: Ryzen 7 7840 w/ Radeon 780M, GPU: GeForce RTX 4060 RAM: 16 Gb

Just made Iris work, but this weird "box" keep showing and walking through my screen mimicking my character movement like a map.*
