For OpenJDK, this seems to be a known implementation bug in the XLib library on Linux:
For other Swing applications that you can choose look-and-feel in, they may have a workaround as described there. But since the link seems to have recently been updated (2015/10/13), hopefully they are working on a longer-term solution for the AWT applications (like ImageJ)...

The Windows Installation instructions suggest to uncheck "Disable display scaling on high DPI settings", but this seems to have no effect. In developing plugins, it is possible to make dialogs larger by setting them to use larger fonts. In this case, everything scales except the checkboxes.

On a 13 inch, 3200x1800 display, ImageJ “sees” the display size as 1600x900 and everything is twice as big as it would be on a 3200x1800 display. Press “i” (Image>Show Info) get the size of the scaled display used by ImageJ. It’s in the line that starts with “Screen location:”.
