Firefox 100, Xclick hit wrong place

Under Firefox 100, Windows10, Xclick command recognize correct the button, but hit wrong place

Here is MWE:

{
  "Name": "Test",
  "CreationDate": "2022-5-9",
  "Commands": [
    {
      "Command": "open",
      "Target": "https://cgi-lib.berkeley.edu/ex/fup.html",
      "Value": "",
      "Description": ""
    },
    {
      "Command": "XClick",
      "Target": "name=upfile",
      "Value": "",
      "Description": ""
    }
  ]
}

This code is supposed to click on upload button, but in my case it hits to far on left and down. How to calibrate it?

Here’s the screenshot during Xclick action (recognizing correct, but clicking wrong place)

Hi, works for me with Firefox 100.

Can you test in Chrome? For me, it works in Chrome and UIV 7.0.11, too.

In Chrome it works fine. but only in single-monitor configuration. Plugging in second monitor makes the same bug. In Firefox does not work in any condition - single or double-monitor, both miss the button just with bigger or smaller mistake.
