Remote Desktop Client May Releases causing problems when moving App to another Monitor.
We experience the same. Single screen workspaces have no issue, but multi monitor is occasionally bugged when logging in through the Remote Desktop client.
Display either freezes on one screen and the other responds, or one freezes and the other stays black. Way to quickly solve it (though it's not a solution!) is to click the square on the white bar on top of the screen to go in windowed mode (not minimize!) and then go full screen again.
Usually solves it.
Also had an occasional glitch that both screens ended up on one monitor, making them incredibly small ofcourse on the top half of the (left) screen.
Hope this can be remedied. Ever since the blue bar got replaced for the (imho not so pretty) white bar, this issue has been persistent.
Note: Computer has the most recent updates and Remote Desktop client and also the latest video drivers from Intel.
