VS 2017 Title Bars Overlapping When Full Screen and Opening another application

We have a VB.Net application that opens Microsoft Excel, Outlook.
When the base application opens Excel or Outlook, the title bars become garbled and unusable ( See 3 example in attachement/photo)

We run windows 10 Pro 1809 on Dell 3500 laptops

Has anyone experienced this before and found a way around it?
