Recently upgraded Office to the standalone 2021 version.
After doing so when I remote connect to the PC (with screen off) and open Outlook/Word there are missing elements on the screen (see screencap).
This only happens with Office 2021, everything else works as expected.
If I turn the PC screen on the Remote PC on those missing elements suddenly appear.
Any idea what the problem is?
Host version 7.1.5.0

Hello Gaz,

Thank you for your message.

Please try enabling the Use legacy capture mode feature in the Host Settings -> Other tab and .
Please make sure to restart Host after enabling the feature in order to apply the changes.

In addition, please also try enabling the Capture alpha-blending windows feature in the Connection Properties -> Additional properties tab and see if this helps to resolve the issue.

Hope that helps.

Legacy Capture Mode was already enabled.

Tried enabling the Capture Alpha-Blending Windows Feature and it made no difference.

Thanks again Pauline
Unfortunately none of the suggestions mentioned had an effect.
The graphics card is a GTX 770 if there are any known issues with that?
But it was fine until the upgrade of Office (previous version of Office didn't have this issue)

Hello Gaz,

Thank you for the update.

Unfortunately, there are currently no known issues related to the MC Office and we haven't received any other reports regarding similar issues. Perhaps, something in the latest version might be causing the issue.
I'll forward the issue to our development department to see if we're able to reproduce the issue in our environment and implement a fix for it in our future updates. Sorry for the inconvenience.

Please let us know if you have more questions.
