Using Eclipse SDK 4.2 M5 on Kubuntu: Some lists have some unpleasant scrolling behavior: Preferences > General > Keys 1. in the command list scroll using the mouse wheel or scrollbar 2. click to select a command 3. list snaps to top, so I don't see what I just selected (except for the details below, which show that selection worked OK) Editor Ctrl-E: 1. scroll using the mouse wheel or scrollbar 2. try to click on an entry that just became visible 3. as soon as the mouse moves. the list starts semi-random scrolling, so hitting a specific entry is hardly possible. The second behavior looks like it's also trying to jump to the top but as soon as the movement starts it is stopped by a new implicit selection under the mouse pointer. Random scrolling only ever happens towards the top. FWIW, I'm using the "classic" scheme due to usability issues in the default scheme.
Does this happen in 3.x?
(In reply to comment #1) > Does this happen in 3.x? I hadn't noticed, but you may be interested in hearing that this got introduced somewhere between 3.8M3 and 3.8M4! I also tried 4.2M2 where the Keys preference page behaves well, but in that version Ctrl-E in editors still suffers from lack of scrollbars ;-P Right now I didn't have more versions at hand to narrow down further.

Only chance to use the Ctrl-E list is via the keyboard.
The first issue about Preferences > General > Keys was reported as bug 376474 I cannot reproduce the second issue as the Ctrl+E list closes whenever I select an item. Actually there are at least 3 "editor-lists" - Ctrl+E - Shift+Ctrl+E - Ctrl+F6 with or without shift But they all work as expected for me. Version: 4.2.0 Build id: I20120608-1400

If you closely follow comment 0 you see that the problem is *before* selecting an item, not after. I still see it in 4.2.0. > Actually there are at least 3 "editor-lists" > - Ctrl+E That's the buggy one. > - Shift+Ctrl+E no problem here. > - Ctrl+F6 with or without shift > But they all work as expected for me. I didn't know this one but combination of mouse-wheel and mouse-motion is broken also here.
ups ... admitted, you were faster :-)
I can confirm issue 1 (keys) in Ubuntu + Eclipse 4.2.1 I think I have seen issue 2 (ctrl-e) sometimes, but can't reproduce it now on 4.2.1. I do have another scrolling issue: If you use git history, and search, scrolling is bad too. The item you 'found' disappears from the viewable part. Scrolling is not to top, but neither to the correct place. (bug 388768) Introduced also in 3.8 / 4.2, not in 3.7
