High CPU Usage in WinUI App When Screen is Locked on Remote Desktop Due to DWMCOREI.dll #9703

Describe the bug

Environment: Operating System: See screenshots Driver version: See additional context

Description: When running Xelion, a WinUI application on a remote desktop, there is a significant increase in CPU usage when the screen is locked. After thorough investigation, the high CPU usage was traced back to the DWMCOREI.dll, which is used by the WinUI application. We have found a quick workaround to fix this. For more info about the workaround visit the following link

Steps to reproduce the bug

  1. Connect to a remote desktop. Use the remote desktop app you can download it here.
  2. Install Xelion 8 using the following link: Xelion 8 Installer.
  3. Run the Xelion app.
  4. Log in to the Xelion app. For credentials, you may contact me.
  5. Open Task Manager.
  6. Lock the screen (e.g., press Windows + L).
  7. Unlock the screen.
  8. Observe in Task Manager that the Xelion app initially uses a high amount of CPU power for a short period before decreasing. However, when the screen is locked, the app continues to consume a high amount of CPU power.

Expected behavior

The CPU usage of the WinUI app should remain consistent and not significantly increase when the screen is locked on a remote desktop.

@riverar I think KB4522355 will not solve this issue. It happens in a later Windows version that was fully patched. Apart from that, the issue is somewhat different, although both related to DWM.
