Problem description: TextBox shrinks after running application on 300% DPI.

Expected behavior: TextBox was scaled well when running application on 300% DPI.

Minimal repro:

Set Windows DPI as 300%,.
Open the attached application. WinFormsApp3.zip
Build and run it.
Observe the size of TextBox.

Some winforms controls are Font scaled and reset control height to Font height, no mater what the bounds were. Expecting different category controls to align with each other when scaled is a complex issue. This needs breaking changes.

@Zheng-Li01 Does it behave as expected when everything is using DPI Scaling?

Zheng-Li01 commented 3 years ago

@merriemcgaw, there have same behavior between design time and run time when creating & running the project both on 300% DPI scaling.

Zheng-Li01 commented 3 years ago

@merriemcgaw, the issue also can reproduce when setting the AutoScaledMode property value as DPI.

@Zheng-Li01 Thanks!

Planning to confirm with the Widows team on expected behaviors.
