It updates as soon as you move the mouse, but indeed it doesn't update right after the jump. It's because when we move the cursor there's no actual low level keyboard input to react to. Wonder if we need to fake it.

I assume a SendInput call with MOUSEEVENTF_ABSOLUTE is the way to go here. https://learn.microsoft.com/en-us/windows/win32/api/winuser/ns-winuser-mouseinput

It’s possible SendInput might make the problem worse with the LittleBigMouse ticket - I think LBM looks for the first mouse event on a new monitor and scales the position and moves the cursor again to its final dpi-scaled position - at the moment Mouse Jump moves the cursor ok with LBM enabled but LBM “skips” it when you move it, whereas it might skip it as part of the Mouse Jump if sees the synthetic SendInput event above, which would mean it would land in the wrong place rather than land, then skip.

Its glitchy behaviour either way, but I guess it depends on what’s least undesirable all round…

I’m happy to take a look if no-one else has started working in this yet…

Fixed in 0.69 which was released in the start of April 2023.
