Win11 preview version 26XX dynamic wallpaper invalid

[Chenlei534]

Describe the bug
Win11 preview version 26XX dynamic wallpaper invalid

To Reproduce

1. After compiling with the latest code and running it on Win11 preview version 26xx, it was found that the previous modifications to the window hierarchy structure that caused the dynamic wallpaper to become invalid did not take effect。

2. As shown in the picture, the video window has been successfully added, but the dynamic wallpaper is not displayed。

I'm also having this problem, and I'm on the 26016 version of win11 and the live wallpaper doesn't come out

[everything411]

That is strange, because I'm on 26016 too and it works.

[rocksdanister]

Maybe he has Windows HDR turned on?

[everything411]

lively works well for me when hdr turned on.

maybe windows widgets? i disabled widgets from group policy. i will have a test later

update: widgets also ok.

so strange

[Yvonne5531773]

same issue, any update?

[rocksdanister]

@Yvonne5531773 The release build does not have the patch yet, did you try the test build provided here:
#2050 (comment)

[Yvonne5531773]

@rocksdanister I have tested the latest build, and it works fine. However, when switching the video player from mpv to Windows Media Foundation (WMF), play fails. I have tried mpv and VLC, and they work correctly, but WMF is not functioning. May I know the reason for this issue?

[everything411]

Confirmed that WMF Player is not working properly with the new window layout, while mpv, vlc, cef and webview2 all work well. I've checked the window styles among these different backends but haven't noticed something suspicious.

[sergodesit]

On build 26040.1000 there is a video overlay and does not interact with the desktop.

[Yvonne5531773]

@rocksdanister Do you know why WMF doesn't work, but VLC and MPV do? Can you provide specific reasons? Thanks~

[rocksdanister]

I don't use Windows insider builds.

[TheTechWiz5305]

I'm on Build 26058 and it still isn't fixed

[rocksdanister]

Because official release is not updated yet, there is unofficial one #2074 (comment)

Lively does not officially support insider builds since its subject to change too frequently, this issue tracker is open because a user submitted a patch.

[keshka]

The issue persists on build 26080.ge_release.240308-1400

Got this information from Microsoft:

As Windows evolves to help deliver the best customer experiences, we have changed how the Background renders in Windows to enable new scenarios such as HDR Backgrounds as announced in Windows Insider.

When the desktop is split out from the list view window (aka the "raised desktop") we no longer create multiple top-level HWNDs to support this scenario. Instead, the top-level "Progman" window is now created with WS_EX_NOREDIRECTIONBITMAP (so there is no GDI content for that window at all) and the shell DefView child window is a WS_EX_LAYERED child window. When the desktop is raised, we create a child WorkerW window that is z-ordered under the DefView that will render the wallpaper. The DefView window will draw mostly transparent with just the icons and text.

If your application forces the "raised desktop" state, it will now need to create its own WS_EX_LAYERED child HWND that is z-ordered under the DefView window but above the WorkerW window. This window should likely be a SetLayeredWindowAttributes(bAlpha=0xFF) window so that you can do DX blt presents to it and not suffer performance issues.

In windows pro 11 24H2 Canary channel not working? I have errors and can't install theme

[sergodesit]

Live wallpapers do not work on the Canary channel, they are not synchronized with the desktop, on a blank desktop there is just a live picture without the ability to control. Отправлено из приложения "Почта<https://go.microsoft.com/fwlink/?LinkId=550986>" для Windows
