Created attachment 229217 [details] Screenshot taken while dragging When dragging editor tab to change the order of editors, a black vertical line indicating the insertion location appears but doesn't move with the cursor (see the attached screenshot). As a result the user doesn't know where the tab will be inserted and whether the dragging works or not. This is a regression from 3.8.
This works for me on Mac using 4.3.0 I20130605-2000. So this could be a Linux/GTK specific issue.
Works for me on Linux Ubuntu 11.10 GTK 2.24.6 with 4.3RC2
(In reply to comment #2) Hmm. In 4.3RC4 the black line sometimes does move but then it gets stuck and stops following the cursor. Does it move for you along the whole row of tabs?

Does it move for you along the whole row of tabs? I can see the problem also if I move around a lot. I've noticed that if the editor is maximized it can happen more often. Also, it sometimes works ok, but then I move the cursor around the rest of eclipse and then go back to the list of editor tabs, and it won't work anymore. Definitely something not working well.
This is a Linux specific issue. Works fine on Windows.
Works well on Fedora 19, for both 20130606-0932 and for Fedora Eclipse build. The only difference I've noticed is that the marker is bright green. Steps to reproduce the problem would be nice here... Alex, any idea?

About the color it is probably theming issue.
This is probably an issue with Ubuntu's choice of black for tooltip background color. Any time I've found black UI elements in Eclipse, they've been fixed by using a custom gtkrc that sets tooltip_bg_color to something else (like #fefefe). In this case I'm on ubuntu and with my gtkrc I see the correct green highlight.

The problem is not the color of the highlight but the fact that the highlight gets stuck and rarely moves with the cursor. In fact, the vertical bar highlight would not provide for a good user experience even if it moved properly. Compare with the tab dragging experience in Chrome where it is a truly WYSIWYG experience.
I still get this issue with 4.6-I20160301-1230. I found that if the window is not maximized the issue is easily reproducible. Using Ubuntu 15.10 and Fedora 23. Although on Fedora 23, it seems to happen whether or not it's maximized.
This seems to be solved now with bug 492842 fixed. Should this be closed?
