ADDITIONAL SYSTEM INFORMATION :
Windows 10 FullHD notebook or monitor, with Scale 125%

A DESCRIPTION OF THE PROBLEM :
I am working on a JavaFx application which use canvas to represent a diagram. The canvas is painting text using graphicsContext.fillText(). In the image below the canvas is on the right, on the left is a Label using the same font. The issue seems to be on FullHd Windows notebooks, where Windows sets by default a scale 125% in Windows display settings. The other components like tree, buttons, etc. are looking fine, affected is only the Canvas where I use graphicsContext.fillText()

For the sample image please look the link on
