      Description

      On HiDPI displays, the sequence title and residue font rendering is being made at a lower resolution and then being upscaled as a bitmap graphic.

      The upscaling factor might be ascertained from the sun.java2d.uiScale property (see comment https://issues.jalview.org/browse/JAL-3552?focusedCommentId=23566&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-23566 )
      and used to scale the font size being used. However, then the upscaling of the graphic layer will not be needed -- can it be turned off for just this panel?

      Also, in the linux screenshot, the text under the annotation rows does not appear to be anti-aliased either.
