My experience with a multitouch screen on a Raspberry Pi 5

Hello,

I've recently tried to use O-S-C with a multitouch monitor on macOS. I couldn't get the touch data into O-S-C so I've tried to use a Raspberry Pi 5 as a gateway.

My current conclusion is that it's not as performant as a Windows setup with the very same touchscreen. As I work with my screen in portrait mode, I could manage to set the right orientation at boot. But then the orientation of the touch overlay had to be changed separately. I could do it too.

However the reactivity to touch is not so good. It's slow, some touches are missed. Currently it's of no use for me. So in the near future I'm going to use a small Windows computer to handle the touchscreen, either a NUC or a laptop. Except if I can find some information to tweak the touch response of the RPI.

It might be worth testing with different versions of chromium (instead of the one provided by raspi os) or with firefox.

Indeed but in the immediate future I am going to use a Windows laptop as gateway.

I could test a few browsers and the performance is not different from one to the other. But the problem is not so much a matter of speed but rather a matter of driver I guess. Note that X11 and Wayland provide the same performance. I don't have time to dig into this now. Maybe later if I can't find another solution.
