Difference: HipeKnownIssues (193 vs. 194)

Using high-density displays with HIPE makes Java 8 display unreadably small text and icons on Windows and Linux

Ticket number: None; Third-party.

Versions affected: All HIPE versions

Description: Java Swing does not render text and icons correctly scaled on displays with a pixel density higher than 100 pixels per inch (ppi) on Windows and Linux, causing UI elements to be very small.

Root cause: Oracle only provided pixel-dense fixes for Retina displays on macOs, leaving Windows and Linux with an inconsistent configuration. (Java tells the Operating System that it is pixel-dense aware but actually it does nothing, leaving the UI elements at their original scale.) This has been fixed for the future release of Java 9 ( JEP-263).

Workaround: There was a JVM argument to prevent Java stating that it is HiDPI aware on Windows: -Dsun.java2d.dpiaware=false . Unfortunately, it doesn't work with Java 8 because Oracle has added to the java.exe manifest file the following statement, overriding the JVM argument:

  <asmv3:application> 
    <asmv3:windowsSettings xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings"> 
       <dpiAware>true</dpiAware> 
    </asmv3:windowsSettings> 
  </asmv3:application> 

If you do not mind modifying your Java installation, you can edit the manifest of java.exe, javaw.exe and javaws.exe with a tool like ResEdit and set the dpiAware value to false. Then Windows will scale UI elements automatically to the proper size.
