Steps to reproduce

 

Local Machine Reproduction

 

1) Open a session of Nuke maximized on the desktop

 

2) Lock your system ( Windows key + L ), and click "Switch User".

 

3) Log back into your account

 

4) Open Nuke's Preferences window

 

 

Remote Desktop Reproduction

1) Open Nuke on the host machine.

2) Use Windows 10 Remote Desktop on another machine to remotely access the Host machine.

More information about how to use Remote Desktop can be found on the following page:
https://support.microsoft.com/en-gb/help/4028379/windows-10-how-to-use-remote-desktop

3) Open a dialog window, for example the preferences window (Edit > Preferences), and notice it is a bright grey colour.
The change of colour can now also be seen on the host machine, and not just through Remote Desktop.

Workaround
This can be solved by closing Nuke and reopening it.  The GUI color does not change other functionality.
