That makes sense.
Submit a bug report.
(Fred already told me about a problem with the mouse library on Linux.)
As for the compilation issues, I'll talk to him about it.

I run Linux as a virtual machine under Parallels (macOS)
Here the MouseDeltaX/Y function also causes problems and is very inaccurate. Thus, all examples with MouseDelta run very badly.
MouseX/Y work well

P.S.
It looks like ScreenGadget Library is used internally for Mouse position MouseDeltaX/Y. Otherwise the problem would not be.
Is it so and why. If necessary, use MouseX/Y absolute position.
