MotionBlurFilter doesn't work with WebGL. With preference: 'webgpu' it works. #489
Description
The MotionBlurFilter doesn't work when initializing the Pixi app with preference: 'webgl'. With preference: 'webgpu' it works as expected.
The issue is visible here. Just replace webgpu with webgl. https://stackblitz.com/edit/vitejs-vite-pe8rxx69?file=src%2Fmain.ts
In the Filters demo it also doesn't work. https://filters.pixijs.download/main/examples/index.html?enabled=MotionBlurFilter
Tested with "pixi-filters": "^6.1.0" and "pixi.js": "^8.7.2" on Chrome on Windows.
