TextBox PlaceholderText is no longer centered correctly in v1.6.0

[Balkoth]

Describe the bug

In WindowsAppSDK 1.5 <PackageReference Include="Microsoft.WindowsAppSDK" Version="1.5.240802000" /> it looks correct like this:

In v1.6 <PackageReference Include="Microsoft.WindowsAppSDK" Version="1.6.240829007" /> it suddenly looks like this:

So whatever has changed it messes with the positioning of the PlaceholderText.

Steps to reproduce the bug

<Window
  x:Class="TextBoxTest.MainWindow"
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Not fixed.

Does anyone even care? This breaks the whole styling and makes the app look ugly now.

I just got around to updating our application from 1.5.7 to 1.6.1 and immediately noticed the same issue. The CheckBox control also seems to be affected, as it displays the content at the top instead of centering it vertically.

Have you found any workarounds for this issue?

[Balkoth]

Unfortunately not. Are you too on Windows 10?

[Trix07]

Yeah, I'm still on Windows 10. I tested it on a Windows 11 machine, and it works fine there, so it seems to be an issue only affecting Windows 10 machines.

Thought so...
