Here's another bug report for Swing on Aqua/MacOS. In recent Java versions (6-12 months, not sure), trackpad scrolling in any JScrollPane has become extremely jittery, as demonstrated in the following video: https://vimeo.com/151843642 The source code for the example app used can be found here: https://gist.github.com/eirikbakke/09a090ab8052d38c8c87 Note that the "implements Scrollable" business is not necessary to trigger the bug, I just did it to set the getScrollableBlockIncrement to something higher than 1 so that you'd see the jitter clearly on a video. This happens in any app that uses a JScrollPane, including the NetBeans IDE's code editor and other scrollable panels, as well as in trivial apps like the linked example. The bug occurs consistently, with or without external monitors attached, at any resolution, and with or without simulated retina mode enabled. I'm on a 13-inch mid-2012 MacBook Air.

So you scroll in both direction at the same time. Whoa, great catch! That's the problem! This is definitively not the right behavior on trackpads; often the user will not scroll exactly horizontally or exactly vertically. And it interacts very badly with the momentum feature of the trackpad; see for instance the video at 1:13, where the viewport is jittering up and down _after_ my fingers have left the trackpad. The "left-to-right is scroll up" feature is not how native apps work on MacOS, so my guess would be it could simply be disabled on MacOS. Note also that when scrolling with the trackpad in native MacOS apps, the OS makes a decision as to whether the scroll is vertical or horizontal, and then scrolls in that direction only. The cut-off is 45 degrees, giving the user plenty of wiggle room. You can never scroll truly diagonally except by zig-zaging. -- Eirik On 1/19/16, 11:50 AM, "Sergey Bylokhov" > wrote: I am not sure that this is regression or a bug.

Presumably Apple decided that the use case of exact horizontal/vertical scrolling would get priority over smooth diagonal scrolling. It could also have ergonomic reasons, as it allows exact vertical scrolling without the user curling their fingers even when their hands are on the side of the trackpad, as they are when aligned with a MacBook keyboard. In any case it's a separate issue from the jitter bug, of course. -- Eirik On 1/20/16, 9:13 PM, "Sergey Bylokhov" wrote: >Hi, Eirik. >Did you create a bug at bugreport.java.com? > >On 20/01/16 00:51, Eirik Bakke wrote: >> >> The "left-to-right is scroll up" feature is not how native apps work on >> MacOS, so my guess would be it could simply be disabled on MacOS. > >I will take a look what we can do here.

This crash happened while doing a tab pane drag-and-drop operation in a NetBeans Platform-based window system to relocate a sidebar in the window layout. In this case the NetBeans window system does an offscreen paint of the dragged panel (which contained a JProgressBar); this may have confused the painting code.
