Broken signal. Corrupted frames. Controlled chaos.
Bad WiFi is a real-time Minecraft Java shader effect that recreates the visual artifacts of unstable internet connections, damaged video streams, and low-bitrate compression. Designed for cinematic projects, machinimas, horror maps, and stylized gameplay footage, it brings authentic digital distortion directly into Minecraft.


📡 Highlights
Realistic packet loss simulation. Frames break apart into fragmented blocks, mimicking the appearance of interrupted video transmission and unstable network connections.

Macroblocking & compression artifacts. Large compression blocks, corrupted image regions, and bitrate degradation reproduce the look of heavily compressed online videos.
RGB signal corruption. Subtle chromatic offsets and color channel separation create the appearance of damaged digital signals and transmission errors.
Ghosting & frame persistence. Previous frames linger momentarily, producing realistic streaming desynchronization and buffering effects.
Dynamic glitch patterns. Artifact placement changes continuously, preventing repetitive distortion and creating a believable corrupted-stream aesthetic.
Performance-friendly implementation. Designed to achieve convincing visual corruption without excessive GPU overhead.
