Yes, thanks Kirill. The VM argument -Dsun.java2d.uiScale.enabled=false alleviates the issues although Squiggle is considerably “smaller” overall.

I had Windows display settings to scale 150% but when I put it to 100% I found that the issues went away (albeit that it’s almost impossible to read icon text etc.). So, is there anything that can be done about this at the Java level or the Batik level? Maybe some command line arguments to handle the hi-DPI scaling?

There doesn’t appear to be any of the aforementioned degradations in Batik itself; the issue is with which version of Java you run Squiggle with. I have found that all Java versions after JDK 8 show this slower scaling and poorer rendering quality. Even just the splash screen is very noticeably more pixelated and SVGs themselves are more grainy. I’ve attached some screenshots of both the splash screen and the tiger SVG using Java 8 versus Java 10. Does anyone know why this is the way it is?

Is it between the same Operating System? And same OS version? Please state which one/ones are they. 2. Is it between the same JRE/JDK (Oracle/OpenJDK/etc.)? And same versions? Please state which one/ones are they. Also, given it's a quality difference, one or two pairs of screenshots between same content in the two environments would quite improve the explanation.

What are the major changes that may have resulted in this degradation?
