MagicPad 2 WebRTC livestream freezes on all browsers - anyone else experiencing this?

I'm having a frustrating issue with my MagicPad 2 and I'm hoping someone here has experienced something similar or has any ideas. When watching WebRTC-based livestreams, the video freezes while the audio keeps playing. Sometimes it's just micro-lags with quality drops, sometimes complete freezes lasting several seconds. It happens randomly and I can't predict when. I've tested Chrome 143, Edge 143, and Firefox 146. All three have the same problem. Edge was better initially but now lags just as much. I've tried everything I could think of: disabled WiFi+, changed DNS to Google and Cloudflare, tested different WiFi frequencies, cleared cache, locked refresh rate to 60Hz (made it worse), tested GPU overlay settings in developer options, enabled WebView multiprocess, disabled QUIC protocol in browser flags, and many other flag combinations. Nothing provides a permanent fix. Here's the interesting part: my Poco F6 with the exact same Snapdragon 8s Gen 3 processor works perfectly in the same WiFi network on the same streaming sites. Zero issues. The only difference is HyperOS versus MagicOS. My system: MagicPad 2 ROD2-W09, MagicOS 9.0, Android 15, Build 9.0.0.175(C431E1R3P3). Everything up to date. My theory is that MagicOS has issues handling UDP-based protocols. WebRTC relies on UDP, and that's exactly where it breaks. TCP-based streaming like VOD content or YouTube works flawlessly. Has anyone experienced similar issues? Is there a browser that handles WebRTC properly on MagicOS, or any system setting I might have overlooked? Any help is appreciated.
