I installed the Windows April 2018 update for Windows 10 yesterday. Today, I opened Windows Live Mail to find that the graphics have mutated in a way I can only describe as "weird". Part of the text from the left hand side, e.g. the email header, the contacts list etc, is reflected backwards and flipped 90degrees, appearing along the bottom of the screen above the task bar. Other programs such as Excel, Word, Photoshop, Edge and Mozilla seem to be functioning ok. The problem seems isolated to Windows Live Mail. I can't attach an image of this as it shows too much personal information but below is a snip of how the contacts window looks now. It's the same if I open a new folder in Windows live too.
I'd be grateful for some explanation or help how to fix it!
