           Summary: [r600] Screen update problems when scrolling to the
                    right in Java applications
           Product: DRI
           Version: XOrg CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org

Screenshot showing garbage area after scrolling to the right.

Example application for testing: TV Browser (see screenshot)

When scrolling to the right, the contents of the scrolled area become garbled.
Moving the mouse pointer over elements in the garbled area apparently causes a
redraw of that element, fixing the issue, but the other elements are not
redrawn.

This does not occur when scrolling to the left. If the area is garbled and one
scrolls to the left, everything is redrawn and appears correctly again.

This may be confined to java applications, and I only noticed this in tvbrowser
(http://tvbrowser.org). Unfortunately I don't have any other java applications
available to test.


Reproducible on the following hardware:
ATI Technologies Inc Mobility Radeon HD 3400 Series
ATI Technologies Inc Device 6719 (HD 6950 Cayman)

I can't seem to reproduce this on an RS880. Please attach the full Xorg.0.log
file.

Here you are. For me, it's easily visible when dragging the horizontal
scrollbar to the right.

What JRE/JDK are you using, and which rendering backend does it use? Did you
make any changes in TV Browser's graphical settings? ...

Ideal would be some kind of simple test app or replayable trace which could be
used to reproduce the problem independently from all such variables.

> What JRE/JDK are you using, and which rendering backend does it use?

I'm using sun-jdk-1.6.0.27 (amd64).

> Did you make any changes in TV Browser's graphical settings? ...

I've started with a clean profile and did not change any settings.

I'm sorry, but I can't provide this. This could of course be a bug in
tvbrowser, as I don't have such issues with eclipse, but that may do the
rendering in a completely different way after all. I've learned in the
tvbrowser forum that the application has some display problems, though nothing
that would compare to my issue here.

I will try to reproduce this with the nouveau driver *with the same config* and
report back, just to be sure. Last time I tried the garbage problem did not
occur though that was quite a while ago and may have been with an older version
of tvbrowser. Unfortunately, it will take some time until I get to a machine
using nvidia hardware.

Thanks for your help so far.

garbadge in gnome-terminal

This problem also shows in ubuntu after upgrading from natty+xorg-edgers to
oneiric. (See attached screenshot)

Then it not only happens in tvbrowser (there also).

The corruptions appear randomly all over the screen. What can be done to
further investigate - as it is now, I can not seriously work with the system.

Why do you think it's the same bug? It seems rather unlikely.

Please file your own bug with all the relevant information.

Because the tvbrowser corruption happens since the upgrade and I saw the
described other effect additionally - so the problems both started with the
upgrade. But I'll stay away from this bug and just monitor it. Maybe your
interested in the fact, that the terminal corruptions are gone after removing
some remaining packages from the xorg-edgers PPA und that the tvbrowser
corruptions are now still happening, but less often.

No garbage visible with nouveau driver and nVidia Corporation G70 [GeForce 7800
GS] (rev a2). Same versions of JDK and tvbrowser.

I changed the title to be a little more specific ;-)

I'm seeing similar corruption with tvbrowser, however I cant make it 'stick'.
It corrupts only during the scrolling, and as mentioned, only when scolling
sideways to the right. I do however see similar corruption a lot in other apps,
that sticks until redraw. And it seems related to text rendering, not
especially to scrolling. I suspect its the same issue as the corruption looks
quite similar.

I see it most often in the bookmarks bar of Chromium, there it shows up usually
after 1-2 hovers with the mouse pointer. Just make sure the bar is visible, and
add some bookmarks there (with label). Sometimes gnome-terminal also corrupts,
and for example the torrent list in Transmission. When I focus the window, the
corruption disapears (until it corrupts again), probably gets redrawn?

AFAICT it is independent of compositing; it happens in gnome's fallback mode
also, and xfce4 w/ compositing disabled.

Attaching a screen shot that shows both chromium and gnome-terminal corrupting.

Using the same xorg stack I see it on AMD Radeon HD4780, HD5450, HD5770 and
HD6670, but not on Intel HD2000 (Sandy Bridge). Verified with kernel 3.0.x,
3.1.x and 3.2-rc5. No xorg.conf, no weird radeon module options.

The stack looks like this, its basicly pure builds from git, with xorg core
from the 1.11 branch (xorg-edgers PPA on Ubuntu 11.10):

component and start bisecting it.

A couple of new data points:

Option "NoAccel" "true" shows no corruption.
Reverting to an older known good radeon driver version, but on this newer xorg
stack still shows corruption.

So I will now try to focus on xorg core. I'm starting to think this is an issue
with EXA acceleration (which intel is not using, it seems). Setting XAA with
KMS didnt work..

Oh, Option "EXAPixmaps" "false" seems to fix/workaround most of the problems.

Still seeing some corruption while right-scrolling the tvbrowser app, but
everything else seems clean.

Magic worked its way, and this has been fixed recently. I don't know which
component it was, but I can exclude with certainty sun-jdk, tvbrowser, the
kernel and most probably xf86-video-ati.

I think the other types of corruption reported here (chromium, gnome-terminal)
are not related to my issue.

This bug is still unsolved for me. I'm having Nvidia graphics card (Macbook
5,1) and using Ubuntu 12.04 with proprietary Nvidia driver.

It is still there in Ubuntu 12.04 LTS (up-to-date). Here, too, is a pretty
recent nvidia (GTX 660) at work with proprietary drivers (v304.116). All
standard setup coming with the distro, but using the gome classic 2d desktop.

See also https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/1032936 and
https://netbeans.org/bugzilla/show_bug.cgi?id=243407.

A workaround is -Dsun.java2d.opengl=true.

The problem is pretty easily reproducible by installing Netbeans und opening
the file dialog (native or metal theme), going into a large folder like
/usr/share and scrolling right. You see it immediately. You can barely browse
ANYTHING AT ALL.

One hint: it is *NOT* appearing via "ssh otherUserNotRunningX@localhost -Y
.../bin/netbeans", even when explcitily setting sun.java2d.opengl to false.

--- Comment #17 from Michel Dänzer <michel@daenzer.net> ---
If the same problem happens with the nvidia driver as well as with open source
drivers, the problem must be either in generic X code used in both cases, or in
the Java code.
