Bug Mouse click doesn't hit the correct button in some window resolution

Hi,

I create a project in Unity version 2021.3.6f1, and widnow resolution is 1920 x 540:

There are 100 buttons, and all text content is each button index and mouse position.

At first it works perfectly in Unity Editor. But after the project build a window standalone exe, a bug is found.

When I hit buttons before mouse position is (1441, any y), it work perfectly:


But when I hit buttons after mouse position is (1441, any y), it hits upper other button:


There is no any plugins in this test project, just ugui button. And if I change widnow resolution to 1920 x 1080, it works perfectly in window standalone exe:


I also test in other Unity version, then I find it works correctly before version 2021, and it works wrong in others.

Here is my test project:

Please check it is a bug or not, thanks.
