Description ilia 2017-04-06 07:30:26 UTC
I'm debugging a NetBeans Dev application and get annoying UI behavior.

Steps to reproduce:
1) Attach debugger to the application with 20-30+ threads
2) Pause with debugger
3) Go to Debugging view to see stack traces of the paused threads
4) Expand some of the stacks so a vertical scrollbars appears

Every time I expand a new thread the scrollbar position resets to the bottom, so it's really hard to use debugger. The same happens when I try to scroll up using mouse wheel.

Please see an attached gif. Note that only actions I do are scrolling up and clicking left mouse button to expand nodes.
