使用小面积模糊遮罩干扰 RTX HDR，但最大程度不遮住视频主内容

这是一个 Tampermonkey 油猴脚本，用于解决开启 RTX Video 且倍速播放视频时对显卡带来的过度负载
本脚本开源于 GitHub：https://github.com/ChenXiaoming233/RTXVideo-fix
RTX Video 是 NVIDIA 推出的 AI 视频增强技术，专为 GeForce RTX 显卡设计，包括两个核心功能：RTX VSR 和 RTX Video HDR； RTX Video 在开启时会对 GPU 带来一定程度的负载（开启 RTX VSR 尤甚），在常速播放视频时性能开销尚可被接受。但当倍速播放视频时，由于单位时间内视频流流量翻倍，令 GPU 功耗激增且对其稳定性提出了不必要的极高要求，以至于对 GPU 进行降压超频能过 3DMark 稳定性测试但过不了 Bili3xVideoBench 是家常便饭（笑； 原理非常简单，当视频上方出现模糊遮罩时 RTX Video 会自行禁用，借此特性可以在倍速播放视频时，通过在右下角渲染 1px*1px 的模糊遮罩以禁用 RTX Video

English： This is a Tampermonkey userscript designed to mitigate excessive GPU load when using RTX Video while playing videos at increased playback speeds.
The script is open-sourced on GitHub: https://github.com/ChenXiaoming233/RTXVideo-fix
RTX Video is an AI-powered video enhancement technology developed by NVIDIA, tailored for GeForce RTX graphics cards. It includes two core features: RTX VSR (Video Super Resolution) and RTX Video HDR.
When enabled, RTX Video places a certain load on the GPU—especially RTX VSR. This load is generally acceptable during normal playback speeds. However, at increased playback speeds, the video stream throughput effectively doubles per unit time, causing a significant spike in GPU power consumption and imposing unnecessary demands on GPU stability. As a result, it’s not uncommon for a GPU to pass 3DMark stability tests after undervolting and overclocking, yet still fail the Bili3xVideoBench benchmark due to RTX Video’s high demands during high-speed playback. (Quite the irony, lol.)
The principle behind this script is very simple: When a blur overlay appears on the video, RTX Video automatically disables itself. By rendering a 1px × 1px blurred overlay in the bottom-right corner of the video during high-speed playback, the script exploits this behavior to disable RTX Video and reduce GPU load.
