ID 384660 - CentOS7 - Switching workspaces between fullscreen breaks Node Graph layout

Problem summary
When switching Workspaces in Nuke11 on CentOS7 workstations, users have found that their Node Graph is incorrectly resized.
This causes a graphical issue, where their Node Graph tab is smaller than the tabbed window:
​

​

This issue only occurs in CentOS7 environments, testing in other KDE environments does not display the issue.
Additionally, this only occurs on Linux operating systems.

Customer reported version
nuke.n/a

Customer reported platform
centos7

Steps to reproduce

1) Open Nuke 

2) Switch your Workspace to 'Compositing' if not the default.

2) Create a few Grade nodes and spread them out in the Node Graph, so they are out of the window view.

3) Switch your Workspace to 'Floating'

Result: The Node Graph should look graphically wrong, a large section of the Node Graph is now blank.  

NOTE: If the issue does not occur switch between workspaces multiple times.

Workaround
Toggling the Fullscreen mode ( Alt+S ) will resize the Node Graph back to its expected size.
