This looks great. Quick feedback, scrollbars don't work well on my mac mini M1. The bar seems to move twice as fast as the mouse.

Thanks for the bug report! That's the data zoom slider - sounds like a momentum/inertia scrolling issue on macOS.

Which demo were you on? (million-points, live-streaming, or sampling?) I'll test on M1 today and get a fix out.

Really appreciate you taking the time to try it :)

Same issue on Windows - doesn't seem to be OS-related, but a general problem. The sliders and the zoom are basically unusable.

On windows 10, too. Firefox 147.0.1 (You may want to update your "supported" chart! Firefox has WebGPU now)

I also noticed it. On million-points. MacBook Pro M2 on Firefox Nightly 148.0a1 (2026-01-09) (aarch64)

I see the same on Windows 11, both FF and Chrome.
