I am running Team Viewer 9 on both the Client and the Host. The Host computer is Windows 8.1 and the Client is Windows 7 Pro.
When i open applications i just get a Black windows with borders. This happens with numerous applications but not all of them (i think it might be due to how each app is drawn) either way the two biggest ones that bother me are Visual Studios 2013 and Chrome. However the Battle.net launcher will load without issues.
I have attached a screen capture from TeamViewer of Visual Studios you can see the purple border however, you are unable to see the content of the screen. Also even though I have my wallpaper hidden for performance reasons, if i chose to show the wallpaper the content of the app is black not transparent to the wallpaper.
