AVD remote desktop app showing on screen but not responding to clicks until you minimize/maximize

I have a partial solution to this issue which is to disable Advanced RemoteFX Graphics on the AVD via a GPO. This will fix windows becoming unresponsive or in some cases apps freezing the session completely. The symptoms align with some of the issues mentioned here.

According to other research I have performed, it seems like this feature (turned on be default) will malfunction if the app does not conform to certain coding standards. I am not DevOps so please don't ask me how to fix that in the code itself.

Introduction "Use Advanced RemoteFX Graphics for RemoteApp" on Windows Server 2012 and up. This setting enables applications published to RemoteApp to use advanced graphics features. By default, this setting is set to "Not Configured" which will enforce the setting. Some applications do not support these graphics features, causing issues with the way the application/page is loaded through a PSM session with RemoteApp.

2. Expand to Computer Configuration > Admin Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Remote Session Environment
3. Set "Use Advanced RemoteFX Graphics for RemoteApp" to Disabled
