The layout of Controls in HighDpiMode.PerMonitorV2 not as expected

[Aniobodo]

Describe the bug
Some controls, with respect to position/size, are not rendered properly when HighDpiMode is set: Application.SetHighDpiMode(HighDpiMode.PerMonitorV2);

This results in some text being overlaid. A particular example is the text "How are you doing today" which is show as "are you doing today".

To Reproduce
Steps to reproduce the behavior:

1. Unzip and run the attached VS project Entwicklung_VS2022.zip

Expected behavior
The Controls should be properly sized and positioned, so that all text are visible.

Thank you for the bug report, I will have a look as soon as possible

I tried the attached project, it displays just fine.
Could you please share any additional information about your setup?

[Aniobodo]

Please try to run the test on using a large High Resolution monitor (> 96 dpi). This problem may not be noticeable on laptop displays.

I don't have such hardware. Please consider submitting a PR for this issue if possible

@JohannBlais So I finally took a deep dive into the code. Then I found out that the layout/dimensions of the controls are hard-coded to specific values. Some examples are the following lines of code:

this.pnlIcon.MaximumSize = new System.Drawing.Size(68, 0);
this.pnlIcon.MinimumSize = new System.Drawing.Size(68, 0);
this.pcbIcon.Location = new System.Drawing.Point(10, 10); 
maxSize = Math.Max(Convert.ToInt32(this.measureGraphics.MeasureString(ctrl.Text, ctrl.Font).Width + 40), maxSize);
this.pcbIcon.Left = BorderPadding;
this.pcbIcon.Top = BorderPadding;
int captionWidth = Convert.ToInt32(this.measureGraphics.MeasureString(Text, SystemFonts.CaptionFont).Width) + 30;
this.AutoScaleDimensions = new System.Drawing.SizeF(96F, 96F); //Default AutoScaleDimensions of new System.Drawing.SizeF(7F, 15F); provides better scalability
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi;//System.Windows.Forms.AutoScaleMode.Font provides better scalability

The above are part of the reason that the UI is not scalable enough to support high resolution monitor. I understand that there were some scalability limitations with Winform of .NET Framework, but .NET 8+ have received some improvement.

I managed to tweak the code to get a better scalability, but I will not submit it as a PR because it will be a breaking change.
Also, my test with the following project delivered a very good scalability: https://github.com/karenpayneoregon/task-dialog-csharp

I did some refactoring on the code and am now having a look at the autoscaling configuration
