This is still an issue i FileMaker 16:
Thank you for your post and screen shot.
Development and Testing are aware of this issue under Windows with the Creators update. I have attached your post to the original report. When more information becomes available, I will post again.
One customer was able to open a second Inspector window, and sometimes it would render correctly.
I and other developers in my office also see this happening frequently. FileMaker 17.0.2 / Windows 10 Enterprise. Screen res. is at 100%. No plugins.
See The Drop down list on the inspector pane for the state of a button etc. (Normal, Hover, Pressed, In-Focus, etc.) extends off the screen
I have responded to the other link you posted.
