Hi Phil, The fix for JDK-8183399 [1] introduced a new issue: if an external mouse with a real mousewheel is used for scrolling, the new scrollvalues are a factor 10 too low. I created a new bug for this (JDK-8218424) [2] and Jose created a PR to fix this [3]. I'll review that PR shortly.
Can you also review this PR? Thanks, - Johan [1] https://bugs.openjdk.java.net/browse/JDK-8183399 [2] https://bugs.openjdk.java.net/browse/JDK-8218424 [3] https://github.com/javafxports/openjdk-jfx/pull/371
