In different panes, the scrollbar jumps back to the top, causing scrolling to work incorreclty. Example 1: in Java Editor, ctrl-click on some object that is defined in another file (preferably a large one). The other file opens, the cursor is moved to the correct line, then (mainly on larger files, with cursor position not in the top part) the scrollbar is set to position 0 again when it shouldn't. Now if you try to scroll up with the mouse scollwheel, it fails. If you scroll down, you scroll down from the top of the page instead of from the current line number. (this sucks bad time, because you can't quickly scan the context). Only when you start using arrow keys, you jump back to the correct location, and the scrollbar is ok again. Example 2: in the git history pane, type something in the find-bar, so you find something. The commit-list does not scroll to the (first) line you found. If you press next or previous, some scrolling is done, but definitely not the right kind, because the matching item is never visible. Often the scrolling is not even close to the correct point. Neither is it always to the top. (this suck bad time, becaause you can't find what you're looking for.) I'm not sure if they are related examples, buth both involve scrolling and jumping to. It worked in Eclipse 3.7. In 4.2.0 it fails.
PS: using latest Ubuntu, and example 1 is not limited to Java editor. It also happens with other editors.
The issue is on Unity. If I switch to Gnome classic, the issue is gone, and the line is in the middle of the page, scrolling works. Except: the git history pane. That one still hass scrolling issues :(
Hmm, can't reproduce item 1 anymore. So maybe it is fixed in 4.2.1 (or un ubuntu). Item 2 still exists, and it also exists in 3.8, not in 3.7.
maybe realated to bug 370079 ?
The EGit example (2) sounds like bug 385661, right?
yes.
