zipfile with demoproject+ 3 images showing problem

With a TChart on a childform, the legend+Checkmarks does not always scaled correctly when moving from e.g. a 4K monitor to a 2K monitor. 

•	In the attached example I have created an MDI application
•	Project/Options/Application/Manifest/DPI Awareness = Per Monitor v2
•	A MDIChild can be opened by clicking a button on the mainform (MDIForm). 

The MDIChild form contains a TChart which holds some FastLineSeries – Checkboxes are enabled for the Legend in the TChart.


Attached is sample project
2 images showing the legends on 2K and on 4K monitor 
1 image from another program where the scaling go very wrong
