In some (yet unknown) circumstances, I see my active editor showing the line numbers and error markers of another editor. I'll try to add details when I get some more time (steps to reproduce, screenshots...)
Just to know what type of editor(s) have you seen this in ? It's likely more on the editor side than a platform bug.
I got this error by switching between Java editors.
I just had this issue by switching for the JDT editor to PDE's MANIFEST editor: the ruler containing markers and line numbers remained visible on top of the MANFIEST editor.
Anything in the .log?
(In reply to Dani Megert from comment #4) > Anything in the .log? I didn't look at it, and I have so many things in my .log currently that I don't feel like I going to dive in it. Since I can reproduce the issue quite often, I'll be more careful next time I get it and I'll check the log immediately.
Here is an error message from the log when this is happening. Note that I'm using GTK3 on Ubuntu. !ENTRY org.eclipse.jface 2 0 2014-06-25 15:20:10.476 !MESSAGE Ignored reentrant call while viewer is busy.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug. If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
