Description

Please check for a duplicate first
  • I have checked the issue tracker if my bug has already been fixed or answered in another (possibly closed) issue.
Steps to reproduce the issue

On Windows 11 24H2, boot up the pc. After bootup, launch TranslucentTB.exe.

Expected results

The app launches and the taskbar effect is applied (in my case clear)

Actual results

The app launches successfully and appears in the app tray, but the effect is not applied to the taskbar. Only upon exiting the app and relaunching is the effect applied successfully.

Windows version

Windows 11 24H2

Other details

I've tried both booting on start and no boot on start options, and they behave the same way. The app only works when quitting and relaunching. Resetting dynamic state does not work either.

Research direction

Start with taskbarattributeworker.cpp around the state dump reported at lines 1237-1344, then reproduce the first-launch sequence on Windows 11 24H2. Trace why the taskbar remains in its normal appearance on initial launch despite the app appearing in the tray. Done means the clear taskbar effect is applied immediately after the first launch without quitting and relaunching.
