Thanks so much for continuing to follow up on this, the information, and the link for the updates.
Glad to hear the updates seem to have resolved the issues for you 🙂
Got a message back from Dell that they have published an update for the Wyse 3040 terminal firmware as well as an updated Teradici PCoIP package.

We’ve just deployed this update via WMS. We will monitor and report back. Fingers crossed this fixes the issue for us!
