RemoteApp for Windows Server 2012 R2 supports Alpha-Channel and some other optimizations (example: try to resize an application with the native RemoteApp client and then try with the Parallels Client; the experience of the latter is dismal in comparision) that make every RemoteApp work indistinguishably from local application. See: https://techcommunity.microsoft.com...vements-in-Windows-Server-2012-R2/ba-p/248053 The experience is actually impressively better than the one from the regular Parallels Client. With Parallels Client, some splash screen that feature transparency show with black border, some applications that are semi-transparent do not work properly and some other applications that use "Application Rendered" shadows show black borders instead. Parallels do support a setting to use "RemoteApp" instead of the regular client, but it only works for Windows Client. So, the request is to support the same native look "RemoteApp for Windows 2012 R2" provides with the Parallels Client native clients for Linux, macOS and mobile.
