[Bug] NUI gameview permanently reduces FPS

[mizoo852]

Summary

Any resource that captures the game screen through NUI permanently lowers the game's FPS on GTA V Enhanced. My FPS drops from 100+ to around 45 the moment a capture happens, and it never comes back: not after the resource fully cleans up its WebGL objects, not after the NUI page reloads, and not even after the resource itself is restarted. Only completely restarting the game restores normal FPS. The exact same resources and code on GTA V Legacy do not have this problem — FPS either doesn't drop at all or returns to normal as soon as the capture ends.

Reproduced with three independent implementations: itschip/screencapture (0.13.0-beta.5), a custom phone-camera renderer, and the attached minimal repro resource — so it is not specific to any one resource.

Steps to Reproduce

miz-gvrepro.zip

1. ensure miz-gvrepro, join, note FPS.

4. restart miz-gvrepro FPS does not recover.
5. A full client restart restores FPS.
