Today i print cursor pos.x from GetCursorPos.
On my Laptop ninkear ybook 15 ryzen 3200u Windows 11 i get x= -1 ! If my cursor in left side screen.

But could be x from 0 to width screen.

On my descktop computer Windows 10 i get x from 0 to 1920

My question its Windows 11 bug or AMD ?

It's probably a bug in the code. Show a minimal example code that gives the error.

Thats all.

Code:

;my code 32 bits
mousePosit POINT ;as dd 0,0

invoke  GetCursorPos, mousePosit

;I simple do this to fix bug
inc dword [mousePosit]      ;x+1
inc dword [mousePosit+4]  ;y+1

Doesn't compile for me.

Code:

flat assembler  version 1.73.31  (16384 kilobytes memory)
test.asm [1]:
mousePosit POINT ;as dd 0,0
processed: mousePosit POINT
error: illegal instruction.

Perhaps there is an include missing? There is no format either.

replace POINT to dd 0,0

msdn
struct POINT {
LONG x;
LONG y;
}

The code posted can't be assembled.

Please show the exact problem, with code that can be assembled, without needing to guess all the other needed things.
