I built this using Compose Multiplatform, with a C++ backend for the fluid simulation and rendering. Any feedback is welcome!

Very cool. Small bit of feedback - I'd suggest using the pointer events so that the site is compatible with desktop and tablets. It didn't seem to respond to touch events when I tried it.

Thanks for the feedback. Are you using mobile Safari? Can you try changing the pressure sensitivity slider to 0 percent? It might be an issue with wrong pressure detection. I've had to write some custom code for the native iOS version to fix it but hadn't really tested in the browser.

Sure. I dialed the pressure sensitivity down to zero, but it still didn’t work. This was in mobile Safari (WebKit) on an iPad. It definitely works in Firefox on Android, though, so it does seem to be an iOS-specific issue.
