Unfortunately, it seems that some intermediate changes made in Jaunty
during the past week have made things worse for me.
Java performance is good (scrolling, view resizing, etc in IDEA8 is very
fast), however if I open many windows on the same viewport (5+ or
something, especially maximized
I have to come back on my previous comment on the patch. I'm running
Jaunty beta now and Netbeans is back to unusable slow state.
Angryziber can you tell me what your xorg.conf looks like? Or are you
using the default one?

Does anyone tried a latest kernel 2.6.30-rc2 ? It has a lot of changes
in the intel driver.

I have some good news: Jaunty works well for me with both EXA and UXA -
IntelliJ IDEA feels a lot faster even than Intrepid+XAA.
Jaunty has both updated intel driver 2.6.3 and Sun Java 6-13

This has nothing to do with the recent changes in the intel driver, but
with the switch to the EXA acceleration architecture - that many drivers
did recently.

This is not a simple bug, its an architectural change. The intel dirver
switched to EXA, which means hw accaleration.
Although the intel driver does *really* bad with readbacks, this is also java's
fault.
JDK7 hopefully will include the XRender based backend I am currently working
on, which
Thanks for posting this. Unfortunately the performance is still bad (but much
better than without the system property set).
So I hope the guys will fix the intel driver very soon...

Thanks for testing, glad to hear the patch improved the situation.
No, I don't need benchmarks if everything feels well again.

I can confirm that Java: 1.6.0_12-ea; Java HotSpot(TM) Client VM
11.2-b01 fixes the problem for me, netbeans runs fluently with the
default xorg.conf (no Option AccelMethod XAA)
This is a subjective test but it is very clear that the performance is
more or less back to normal. Would you like me
It is related to http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6708580 as
well as the entry on my blog. Its caused by switching to EXA by default in
later Intel drivers, as well as poor X(Shm)GetImage performance.
This problem occurs when switching between hw-accaleration and
As a workarround you can start java with -Dsun.java2d.pmoffscreen=false

This bug is severely hindering my use of Ubuntu as I cannot use the
various SCM and IDE tools I use.
I'm suffering from slow GUIs when using Java. IntelliJ is a culprit, as
well as Star Team. Here are my system details:
-apt-cache policy sun-java6-jre
sun-java6-jre:
Installed: 6-10-0ubuntu2
I'm having the same problem with this graphic card:
00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated
Graphics Controller (rev 02)
Subsystem: Intel Corporation Device 544e
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at 9020
I noticed a huge drop in text scrolling performance between jEdit
versions 4.3pre15 and 4.3pre16. This is especially noticeable with anti-
aliased fonts enabled.
I thought this might be useful information because jEdit is open source
and there are probably fewer changes between two pre-release
A few posts above I wrote that switching to XAA AccelMethod fixed the issue in
Fedora 9 (Intel video driver).
Today I upgraded to Fedora 10 and found out that XAA causes lots of graphical
glitches and makes Gnome not working.
So under F10 I've got to switch to EXA again and make a choice -
any news about this, cause this is really major pita if you happen to
work with java..

you can try Adding the AccelMethod XAA option in /etc/X11/xorg.conf as
discussed above, if that doesn't help you'll have to wait for new intel
drivers/next ubuntu

For me this workaround does *not* fix the issue. The performance is
better than without - but still far away from 7.10.

again, but still seems slower than on Hardy.

Yes, this seems to be fixing the issue for me (Fedora 9, GM965/GL960). IDEA 8.0
looks alive :)
But it's weird, why this issue only appeared for the individual versions of
some applications?
For instance IDEA 7.0.4 worked fined with EXA when IDEA 8.0 died.
