Server 2008 R2 SP1, with Remote Desktop Services.
[Edit: Most] Microsoft updates installed.
Publish Outlook as a RemoteApp, and run it from a Windows 8 client, then open an email. What happens is this:
- The email opens and renders briefly, but the Outlook inbox becomes partly-visible through the email.
- Most of the email is invisible, as if it was in the background, except the border remains visible like an embossed imprint.
- The partly-invisible email is actually in the foreground, the visible Outlook main window is in the background.
Moving things around, clicking on them, causing a refresh, fixes the display. Sometimes waiting does. It happens pretty much every email, but not exactly every one.
Disabling hardware acceleration in the Outlook options doesn't make a difference, nor does disabling add-ins, nor does changing the LoadBehaviour in the add-in registry entries.
Using a full remote desktop session, Outlook works fine.
It happens on multiple Windows 8 clients, too. Not sure about Win 7.
Any ideas, please?
[Edit: Disabling themes, menu animations, bitmap cache persistance, font smoothing, etc. in the RDP connection - all make no difference].
[Edit: Also tried: - Disabling desktop composition, and menu/window animations on the server - Running Outlook in 'safe' mode (with Outlook.exe /safe) - Changing Outlook theme - Connecting to my PC using RDP, then opening the remote app, to try and get around it being my video drivers. - The latest round of Windows/Office updates on the servers. - Removing/recreating my RDS User Profile.
All no change.
Tried on 3x Windows 8 PCs, all exhibit this behavior. Tried on 3x Win 7 PCs, only one does this, the other two appear OK.
