GDM with keys "doubled" and mouse with "lag time" (jumping on screen)

Hello,

I recently installed arch on a 8 core machine.
Since the beginning, after starting the computer, already on GDM screen, the mouse (and keyboard) have a long "lag time". This makes the mouse to make "jumps" in the screen and the keywords pressed to take a while before appearing.
Almost as if something is running in the back.

After starting Gnome, this stops.

This is annoying but I can live with it.

But now, not only this is happening, but in the login screen (GDM), every key stroke is duplicated.
So, if my pass is "PASS", it becomes "PPAASSSS".

And gnome do not recognize the pass, of course.

TO bne able to login, I had to activate the virtual keyboard, but you can imagine how frustrating is to use it with your mouse jumping all over the screen...

Again, after entering Gnome, everything works normally.

Any hints on what can be causing this?

Best regards,
Eduardo

P.S.
If I do a logout, the problem strt again, so, it is something related to GDM I think...
This machine has 8 cores (16 threads), 32 GB memory, 32 GB swap.

P.S.2.
For now, I disabled GDM and am using startx.
