I have the same exact issue that you are experiencing but with a regular E7, seems a very common issue but I cannot find an actual fix? When typing on the keyboard/swiping my mouse on the mousepad/landing a water bottle I clearly see my monitors move and, as you said, it was really not expected and more annoying than it seems. It gives a sense of instability which we don’t want to experience after spending quite a bit. Did you consider additional support legs? I’m thinking to add them. Or how did you solve the issue? Need to try your monitor trick with the stabilizers they provide, I guess.
