If I scroll in the Java editor I see blank lines, see attached screenhshot. This is might be a duplicate of Bug 392700, but this bug is marked as fixed. You can use the same test case to validated that. I'm using Ubuntu 13.04. import org.eclipse.swt.SWT; import org.eclipse.swt.graphics.Color; import org.eclipse.swt.graphics.GC; import org.eclipse.swt.widgets.Canvas; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Event; import org.eclipse.swt.widgets.Listener; import org.eclipse.swt.widgets.Shell; public class ScrollTest { public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); final Canvas canvas = new Canvas(shell, SWT.NONE); canvas.setBounds(10, 10, 300, 300); final Color[] colors = new Color[] { display.getSystemColor(SWT.COLOR_RED), display.getSystemColor(SWT.COLOR_CYAN), display.getSystemColor(SWT.COLOR_GREEN), display.getSystemColor(SWT.COLOR_YELLOW), display.getSystemColor(SWT.COLOR_MAGENTA) }; canvas.addListener(SWT.Paint, new Listener() { int i; public void handleEvent(Event event) { GC gc = event.gc; gc.setBackground(colors[i++ % colors.length]); gc.fillRectangle(-100, -100, 2000, 2000); gc.drawLine(event.x, event.y, event.x + event.width - 1, event.y + event.height - 1); } }); canvas.addListener(SWT.MouseDown, new Listener() { public void handleEvent(Event event) { // DOWN // canvas.scroll(0, 17, 0, 0, 300, 300, true); // UP // canvas.scroll(0, 0, 0, 17, 300, 300, true); // ENTER canvas.scroll(0, 117, 0, 100, 300, 300, true); } }); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } }

In the Java editor I need to scroll with the mouse, "scrolling" with the keyboard works fine.
Increasing the prio, tried to work with it, but this makes the source code editor really hard to use.
I recently observed kind-of the inverse: when scrolling by keyboard cursor up / down only a few line where updated, the bigger part of the editor kept showing stale content. For me wheel or scrollbar scrolling works OK. Could that possibly have the same root cause, or should I file a new bug. Unfortunately, right now I cannot reproduce so I cannot show a screenshot. I'll keep an eye on it. (FWIW: I'm on Kubuntu 13.10)
In Java Editor I didn't notice this issue while scrolling with mouse/keyboard. Tested on Ubuntu13.10 as well as Kubuntu13.10

IIRC the new default is to use GTK2. The fall back to GTK2 happens when the GTK3 version is >= 3.9.0 but both Ubuntu 13.10 and Kubuntu 13.10 have GTK 3.8.6 installed. So, the default will still be GTK3 on these machines.
Interesting bug. Let's try to understand what's wrong. Lars, would you please attach a gtk2 and gtk3 screenshots from your machine (gtk 3.8 or 3.10?) so I can verify I see same problem.
I think that this snippet should have entirely different behaviour on 3.8 and 3.10 and that what I see on 3.10 is related to Bug 421127 .
The issue is related to the overlay scrollbars that are enabled on Ubuntu by default. You can disable them using: export LIBOVERLAY_SCROLLBAR=0 or gsettings set com.canonical.desktop.interface scrollbar-mode normal if you want to disable them globally.
I am also seeing this on Ubuntu 13.10 64bit (no problem on 32bit). setting LIBOVERLAY_SCROLLBAR=0 doesn't fix the bug (the scrollbar is there constantly, so the setting is working for this intended purpose). Scrolling with the mouse wheel works fine, but scrolling with the keyboard and the scrollbar doesn't: the text is garbled (usually the line at the bottom of the window is repeated). Scrolling upward but fine. The problem happens only when scrolling downward.
Created attachment 243910 [details] garbed text (bottom line repeated) Please see the attachment for the screenshot
I meant scrolling upward *works* fine
This is happening to me too. One more workaround : maximize your eclipse, and/or width. If I just make any window where this is happening as wide as possible black area disappears. I think there are two seperate bugs happening here. I'm just seeing black area on the right, when I scroll up or down with mouse wheel or with keyboard. I don't think it's java-editor specific. Happens in a java file, a pom file, a .txt file, and in Preferences->Java->Code Style->Formatter if you scroll in the text screen. I think the garbeled text that some are reporting is a different thing altogether. Of course I might be wrong. Whether ot not in happens in Preferences->Java->Code Style->Formatter is very flaky. It has something to do with if main eclipse is maximized or not. LIBOVERLAY_SCROLLBAR didn't do squat. If anyone wants to know what version of what I've got. please ask.
even better workaround: set this in the environment (to a blank/empty/nothing value). UBUNTU_MENUPROXY you still get a black rectangle, but it's one column wide now. so it's goofy looking, but it doesn't make text editing impossible. still goes away if you maximize eclipse window.
one final update. I'm working good now with all 3 of these set: setenv UBUNTU_MENUPROXY setenv LIBOVERLAY_SCROLLBAR setenv SWT_GTK3 (I use tcsh, sorry translate to bash as you will). Supposefely with Ubuntu 14.something, this isn't needed any more, but I don't feel like upgrading that right now. (I'm running Mint 16, which I think is about the same as Ubuntu 13.10, but don't hold me to that). And I don't really know if all three are needed, or what the exact necessary/sufficient combos are, but this is working for me. good luck.
my problem was fixed by upgrading to Ubuntu 14.
I haven't see that in Build id: N20141214-2000 so I mark it as fixed.

I can see that this bug is marked as resolved/fixed and that is VERY far for true. This critical bug has been going on for a VERY long while, making Eclipse completely unusable. What is your recommendation? Moving back to OS's 3.8.1 version? Netbeans? I just cannot do anything if I can't even see the source code.

I solved this problem with editing the ecilpse.ini in this way: I added the following lines: --launcher.GTK_version 2 after -vm /usr/lib/jvm/java-8-oracle/jre/bin --launcher.GTK_version 2 and befor this: -vmargs regards
After months seeing a black screen instead of my code (I dare you to try it for just one week) and using old versions of Eclipse, I finally managed to 'fix' it. It's not a fix, it's just a trick to keep working while that black screen is fixed. The idea is simple: Eclipse GTK3 is broken, so force GTK2. I created a shell file with these commands: export SWT_GTK3=0 eclipse

Try the latest I-Build from > http://download.eclipse.org/eclipse/downloads It's more complicated than that. The Eclipse team decided to leave old code that is used by some plugins that breaks the environment as seen in the screenshots. As soon as you use one of those plugins you are done. Funny thing is that that old functionality doesn't work with Java8 and has given me issues in the past using Windows. While this problem exists, installing from the Eclipse Marketplace is like Russian roulette. I do not know plugins break your eclipse but you can see an example if you install for example Spring tools suite from the marketplace or if you download Eclipse with it included from this url: http://spring.io/tools/sts/all Right now I'm seeing this issue using Eclipse 4.5.1

Hello, I still experience the seemingly similar problem using the CDT for C++ editing. It happens with mouse whell and line-up/down keys. PageUp or Down helps. export SWT_GTK3=0 did not help, but crashed very soon with java: /builddir/build/BUILD/oxygen-gtk2-1.3.4/src/animations/oxygencomboboxdata.cpp:87: void Oxygen::ComboBoxData::setButton(GtkWidget*): Assertion "!_button._widget" failed. Eclipse version: Version: Mars.2 Release (4.5.2) Build id: 20160218-0600 Computer: CentOS 7 Linux 3.10.0-327.10.1.el7.x86_64 #1 SMP Tue Feb 16 17:03:50 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux Really disturbing bug.
Sorry: "Whell" --> wheel. also scroll bar has same problem. PageUp or Down only helps for those screen regions which are out of the window and are redrawn back in, not for the whole black rect.

Hello, I added --launcher.GTK_version 2 in my /opt/eclipse/eclipse.ini config file, instead of using the environment variable mentioned above. However, Eclipse also crashes when I open the Team > Commit dialog, not only when opening Marketplace as I said above. I vote for reopening the bug, it is really annoying.
(In reply to Karsten Burger from comment #37) > However, Eclipse also crashes when I open the Team > Commit dialog, not > only when opening Marketplace as I said above. Crashing is very different from creating a black area with GTK3 and should be handled by another bug.

Hello Lars, yes, true. I only wanted to point out, that for me there is no good workaround at the moment. I played around and chose different window decoration themes, as someone suggested, but except for the horizontal size of the upper window border nothing changed, and it reliably crashes when opening an "Eclipse Marketplace" or "contex Menu > Team > Commit" dialog.
I found this open bug which seems to describe a similar problem: Bug 469027 - [GTK3] Rendering problems on scrolling
Also crashes when opening Project > Properties
(In reply to Karsten Burger from comment #41) > Also crashes when opening Project > Properties Could you create a separate bug? This bug is not about crashes.
