WebGL information becomes an issue in Cloudflare Turnstile, which checks whether you’re really human; many environments are getting caught by fingerprinting defenses

Cloudflare Turnstile is reportedly flagging privacy-focused browsers, including BadWolf, after suspecting spoofed WebGL data.

The issue can cause login loops or failed checks, and similar compatibility problems have been discussed in other environments such as Firefox and WebKitGTK.

The case highlights a broader clash: anti-bot systems relying on browser fingerprinting can wrongly block users who use anti-tracking protections.

It raises concerns that website access may depend too heavily on fingerprint signals like WebGL and JA3 rather than on user intent.
