Are there any other tricks needed to get this to work? I too have been having this issue for sometime, but have been working around it by using a directly connected mouse when I need to.
I already have the DisplayServerExtraOptions “-oldeventapi 0” setting as a fix for my keychain issue.
In general Xcode and NoMachine just don’t total get along. I have had other issues as well that I have been working around.
I have the above issues as well as the storyboard dragging issue.
I am currently running 5.1.26 on both the server and the clients I have tried, (Windows 10 and ubuntu 14.04). OSX 10.11.4, and Xcode 7.3.
