Visual Inconsistency in MS Form While Zooming in the resolution 150%

### **Description**
When running a basic Windows Forms application on a display with 125% or 150% DPI scaling, the form's border renders as three horizontal lines of varying thickness. This creates a visual inconsistency and makes it difficult to identify the actual form boundary.

### **Screenshots**
* 150% Scaling:

* 125% Scaling:

### Steps to Reproduce
1.Create a basic WinForms application (no custom styling or overrides).

2.Run the app on a display with 125% or 150% DPI scaling.

3.Observe the top border of the form.

4.For exaggerated results, test with 500% scaling.

### Actual Behavior
* The top border appears as three horizontal lines:

* First line: light and thin
* Second line: noticeably thicker
* Third line: thickest

* This layered rendering causes confusion about the true form boundary.

### Expected Behavior
The form border should render as a single, solid line, regardless of DPI scaling.

### Questions
* Is this a known rendering issue in WinForms on high DPI displays?

* Does it impact usability or accessibility?

* Are there any recommended workarounds or fixes?

### Environment

Windows Version - 11
Display Scaling - 125%, 150%, 500% (test)
