One click lag in projects which run on slow armv7 cpu about slint HOT 7 OPEN

Thanks for the report :) Do you know if this is running with X11, Wayland, or directly on the frame buffer?

It runs wayland - weston compositor

Thanks. That's really odd. It sounds like a bug in the touch input handling somehow.

Just out of curiosity: If you attach a USB mouse to the same device, can you reproduce the same issue with the mouse pointer and mouse clicks, or is it just touch?

Problem not happens when using mouse

I tried to reproduce this on an stm32mp157-dk2 running ST's yocto linux with Weston. Unfortunately I can't reproduce the issue there.

Could you try to compile with --features slint/backend-linuxkms-noseat and try to run it without wayland/Weston and see if the issue happens then, too?

I don't often have physical access to the this hardware (I do have remote access, but that's not an option in this case), so unfortunately I won't be able to check until the next few days.
