Change white border around text editor controls

Hi,
maybe someone faced the same inconvenient.

The borders of text editor controls in Windows 11 are displayed in white color and no longer as grey/black. This makes it in Windows 11 hard to visualize the delimitation of the fields. Is there a way to customize / change this?

Thank you!

Well that looks like some generically developed VB.net or C# application and it's either hard coded that way or relying on system settings. Whoever manages the source would need to change it.

I build this sample application. I keep the default settings for controls.
Apparently the look and feel are taken from OS. When the contrast scheme is changed, the controls changes their colors for border and background.
My problem is that with the default theme and default settings the white border it makes hard to see the controls boundaries.
I'm wondering if someone tried to change the white border color.
