Subject: System tray background styling broken on Windows 11 Insider Preview Build 26300.8346 #575

Description

Hi,

First of all, thank you so much for creating and maintaining this amazing mod — I've been using it for a long time and really appreciate your work.

I'd like to report a small issue I encountered after updating to the latest Insider Preview build. I'm not sure if it's caused by a Windows change or something on my end, but here's what I'm seeing:

I'm using the Windows 11 Taskbar Styler mod with the following configuration for the system tray area:

Target: Grid#SystemTrayFrameGrid

Styles: Background, CornerRadius, BorderThickness, BorderBrush, Padding, Visibility

On previous Windows 11 builds, this configuration worked correctly — the system tray area displayed the styled background as expected.

After updating to Windows 11 Insider Preview Feature Update (Build 26300.8346), the system tray background styles are no longer applied. The main taskbar background (targeting Grid#RootGrid > Taskbar.TaskbarBackground > Grid) still works correctly, but the system tray area appears completely transparent.

Steps to reproduce:

Use Windows 11 Insider Preview Build 26300.8346

Apply any background style to Grid#SystemTrayFrameGrid via Taskbar Styler

Observe that the system tray area remains unaffected

Expected behavior: The system tray area should render the styled background.

Actual behavior: The system tray area shows no background, appearing completely transparent.

Note: Other targets in the same mod configuration continue to work normally. Only the system tray-related target is affected.

Please let me know if you need any additional information or if there's anything I can do to help troubleshoot. Thanks again for your time and hard work!

Best regards
