@Olina-Zhang, can you check this in the latest version and see if this is an issue only for VB?

@dreddy-work Verified this on .NET 8.0 latest build: 8.0.100-rc.2.23469.4，this issue may be a problem caused by the ItemHeight property of the TreeView.

1. When adding a TreeView control at 225% DPI, its ItemHeight value defaults to 40, and the item text displays without problems when running the project.
2. However, in the project provided by the customer, the ItemHeight is set to 16, and the item text does not scale well at runtime.
3. Also, this problem can be reproduced in C# projects.
