This might not just be on MacOS; haven't tried yet. Will try elsewhere.

Also slow: https://shi-yan.github.io/webgpuunleashed/code/code.html#5_08_gaussian_splatting_5 (tested in a local build with https://github.com/gfx-rs/wgpu/pull/7250)

After a functional fix, https://shi-yan.github.io/webgpuunleashed/code/code.html#5_04_mega_texture is working, but is also quite slow. Dragging to pan the texture has a significant lag, whereas in Chrome it feels responsive.
