Solution

1. Log in to the APS where the application is published as the administrator.
2. Click and enter Regedit to open the registry editor.
3. Check whether the TransparentWindows registry exists in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Huawei\HDPServer\Rail.
   • If no, go to 4.
   • If yes, go to 6.

4. Right-click in the blank area on the right and choose New > Multi-String Value.
5. Name the registry TransparentWindows.
6. Double-click TransparentWindows. The page for editing multiple strings is displayed.
7. Enter QMShadowWndClass;TXGuiFoundation&playerShadow in Value data based on whether the value data exists in the value data list.
   • If the TransparentWindows registry does not contain other values, add QMShadowWndClass;TXGuiFoundation&playerShadow. See Figure 2.
     Figure 2 Example of registry containing no other values
     
   • If other value data already exists in the TransparentWindows registry, add ;QMShadowWndClass;TXGuiFoundation&playerShadow to the end of the value data. See Figure 3.
     Figure 3 Example of registry containing other values
     

     The value varies with applications. Select a value based on the application.

     • WeChat: EmotionWnd; popupshadow; CMenuWnd
     • WPS: KPromeMainWindowShadowBorder;Qt5QWindowIcon;KDlgBorder
     • NetEase Music: OrpheusShadow
     • QQ Music and QQ Player: QMShadowWndClass;TXGuiFoundation&playerShadow
     • Google Chrome: Chrome_WidgetWin_1&0x96000000
     • WeCom: PerryShadowWnd
     • Sogou IME: SoPY_Hint&HintWnd;SoPY_Status
     • DingTalk: DuiShadowWnd
     • iArtist: Qt5152QWindow&iArtist
     • Sandboxie: SandboxieControlBorderWindow&SandboxieControlBorderWindow
     

     Use semicolons (;) to separate multiple values.

8. Click OK and close the registry editor.
9. Click and choose Power > Restart to restart the APS.
