Note, as i said in my first post....
No problems here with K5's GUI and LPX 10.1.1 and OS X 10.10.2
I just tested the same K5 Lib as you took a screenshot of and again, no such issues....
Nigel,
I wonder if it could be a MacBook Pro Retina issue?
Well, thats a good question...... and one i cannot answer as i don't have a Retina Mac unfortunately.... Maybe Screen Rez related?
However I have seen this issue when a user has incorrectly/manually installed or moved a library..... as the overlay/Graphical resource files (the part that is being drawn over the top of the main screen) have been either placed in the wrong location.... or have been deleted from the original location or are now located in the wrong location and have become unlinked from the K5 lib itself...
The correct initial location for the resources/graphical files should be... (replacing the items between < and > with whatever is appropriate for your setup)
<System Drive>/Users/Shared/NI Resources/Image/<Name of K5 Lib>
As an example, In my case, the Action Strings Resource files are located in
Macintosh HD/Users//Shared/NI Resources/Image/action strings
