### Issue Details

**Steps to reproduce:**
1. Install AdGuard and QQ [1] normally.

2. Enable traffic routing for QQ through AdGuard.

3. When receiving images in QQ, the loading time is excessively long (over ten seconds).

**Troubleshooting Completed:**
1. Disabling all AdGuard features (including "Ad blocking," "Tracking protection," "Annoyance blocking," "DNS protection," "Firewall," and "Browsing Security") did not resolve the issue. The image loading speed only returned to normal when the "Route traffic through AdGuard" option in QQ was disabled.

2. Attempted to add QQ to the "QUIC bypass packages" in "Low-level settings," but the issue persisted.

3. Tested with Rethink [2] instead of AdGuard, and QQ's image loading was normal, suggesting that it is probably not a compatibility issue with QQ.

> [1] QQ is a popular instant messaging app developed by Tencent, widely used in China. (https://im.qq.com/index/#downloadAnchor)
> [2] Rethink is an alternative network app for Android. (https://github.com/celzero/rethink-app/)

### Expected Behavior

Images in QQ should load quickly and efficiently when using AdGuard.

### Actual Behavior

Images in QQ take an excessively long time to load when using AdGuard to route the traffic.
