I also have Constant Screen Freezes too on windows 7 remote to ubuntu linux 18.04.2 with teamviewer 14.2.2558. When i connected and move any program windows will have many shadow follow it. I even have try remote from android device, still have same problem. So I pretty sure the problem is on teamviewer ubuntu side. I have no problem before i upgrade ubuntu linux from version 16.04 with old version teamviewer that still using Wine. please teamviewer team really focus to solve this problem. Otherwise, I may follow the old school VNC way for this case.
