I'm having a weird issue with a winform.

C# winform modified with Microsoft Visual Studio Community 2022 (64-bit) - Preview Version 17.5.0 Preview 6.0 but made with Microsoft Visual Studio 2010
Target from .Net 4.0 to 4.8 (tried to bring it back to 4.0 with no success, the problem remain)
Any CPU

Image 1 is before any change and the result is image 1A. Than I add a textBox as shown in image 2 and get the image 2A as result.

Even if you put it in full screen, the boxes in the botom are not there (not behind the DatagridView either). If I get rid of the TextBox, the problem remain.

It is not a special Textbox
Nothing is link to it. I just put it there and debug it. (release or debug give the same result)
If i remove it, the problem remain. I have to take a copy of the winform without the TextBox to make it work again.

Images will be in order (1 - 1A - 2 - 2A)

Anyone have a clue why this is not behaving as it should ?

Thanks alot !

How about a minimal reproducible example? – Wyck Mar 02 '23 at 21:06

This looks like a high DPI issue in combination with font scaling. You use something different then 100% scaling in Windows and ignored the warning in VS about it? Winforms is old technology and not really able to just work in high dpi environments. – Ralf Mar 02 '23 at 21:21

I remember reading that Any CPU defaults to 32 bit. So you may need to also set 64 bit. – jdweng Mar 02 '23 at 22:22
@Ralf yes i did see this ! I will check for this. – user2448358 Mar 03 '23 at 12:34
@jdweng Since vs2019, Any CPU default is 64 bits – user2448358 Mar 03 '23 at 12:35
Form may contain older version. Try deleting form and add again. – jdweng Mar 03 '23 at 12:37
