# Tabs appear blank and Remote Desktop Manager becomes unresponsive

In Remote Desktop Manager tabs displaying embedded web content may appear blank if the display scaling changes while the application is running. In such cases the application may become unresponsive. The issue usually happens when disconnecting displays or using a docking station. This bug arises from limitations within [WebView2](https://crushonme.github.io/2023/05/23/Webview2-stop-working-after-system-DPI-changed), as Remote Desktop Manager does not currently use the per-monitor DPI awareness mode.

### Changing the high DPI settings

1. In the Windows File Explorer, navigate to ***%programfiles%\Devolutions\Remote Desktop Manager***.
2. Right-click on **RemoteDesktopManager.exe** and select ***Properties***.
3. Go to the ***Compatibility*** tab.
4. Click on ***Change high DPI settings***.
5. In the ***Program DPI*** section:
   1. Enable ***Use this setting to fix scaling problems for this program instead of the one in Settings***.
   2. Ensure the second setting is configured to ***I signed in to Windows***.
6. Click ***OK*** to save the changes.
7. Restart Remote Desktop Manager.
