=> So it seems that it is spending the time in
OS._gdk_pixbuf_scale_simple.
3.) gdk_pixbuf_scale_simple is provided by libgdk_pixbuf-2.0.so
4.) I've verified the differences between the builds of gdk-
pixbuf-2.28.0 for oneiric and precise/raring and found no problematic
difference.
I've verified the differences between the gdk-pixbuf-2.24.1 (oneiric
version) and gdk-pixbuf-2.28.0 (raring) and also found nothing.
5.) However, gdk_pixbuf_scale_simple function calls
gdk_pixbuf_scale...but wait, this function should be performed by
hardware (and not CPU), right?
=> That led me to another investigation.
6.) SWT library
org/eclipse/swt/graphics/Device.java
has boolean named useXRender
It seems that there is some difference in libXrender (oneiric version and all
newer versions)
- Oneiric version sets device.useXRender (boolean) flag to TRUE
- All other newer version sets it to FALSE
=> I've verified this with a simple Java program which was using
libXrender1.so from Ubuntu Oneiric (11.10) and from Ubuntu Raring
(13.04).
When Oneiric's version was used => Device.useXRender flag was set to TRUE.
When newer version of the same library was put on the LD_LIBRARY_PATH =>
Device.useXRender flag was set to FALSE.
Strange...still need more investigation what's going on :-(...

Title:
WebSphere Integration Developer 6.2 (Eclipse 3.4) - BPEL editor is
slow for large windows
Status in “libxrender” package in Ubuntu:
New

1.) lsb_release -rd
Description: Ubuntu 12.04.1 LTS

3.) What you expected to happen: Eclipse window rendering would be working at
the similar speed as in Oneric.
4.) What happened instead: Eclipse was terribly slow.
Conditions: WID 6.2 Linux version is 32-bit. Ubuntu 12.04 64-bit version
installed with latest updates. ia32-libs and libstdc++5:i386 package to make
WID 6.2 working.
WID 6.2 was running smoothly on Ubuntu 11.10 (Oneiric) but that
stopped directly after upgrade to Ubuntu 12.04. The problem is that
window rendering (BPEL editor) started to be terribly slow (CPU at
100%).
I tried to investigate the problem and finally after a few days and nights
I've find out that the problem is in libXrender package.
Since code has not been changed between the two Ubuntu releases, it's somehow
related to how the package is build.
5.) My analysis of the problem:
5.1) Some simple tests first
- Usage of different window environment had no effect (Unity, Gnome
Shell, Gnome Classic, XFCE).
- Usage of latest Xorg versions (xorg-edgers) had also no effect.
- Usage of older/newer nvidia drivers had no effect.
- Usage of xserver-xorg-video-noveau had no effect.
5.2) Compare versions and changelog

5.3) Locate file
Precise: /usr/lib/i386-linux-gnu/libXrender.so.1.3.0
Oneiric: /usr/lib32/libXrender.so.1.3.0
5.4) Compare libXrender library dependency
=> By using ldd utility
=> nearly same output (ie.just addresses are different)
5.5) Filesize comparison (Result: Size differ significantly)
Precise size: 34424
Oneiric size: 38520
5.6) Compare using "file" utility (Result: hashes are different)
Precise: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV),
dynamically linked, BuildID[sha1]=0x62c06ccdf7ede559a439ac33ac35dec40f035a9c,
stripped
Oneiric: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV),
dynamically linked, BuildID[sha1]=0x05ad8f548663c542361448564b6f1c6f881f9e65,
stripped
5.7) Compare libXrender path in loaded libraries (Result: path differs)
Find all dynamic libraries
lsof -p <eclipse process> | grep -E "\.so\.|\.so" | cut -c74-
List library dependency (using ldd) for every loaded library
Result:
- Precise: All used libraries have following dependency:
libXrender.so.1 => /usr/lib/i386-linux-gnu/libXrender.so.1 (0xf69bd000)
- Oneiric: Not tested (already upgraded to Precise). Very likely
/usr/lib32/libXrender.so.1.
5.8) libXrender is used by following loaded libraries

/usr/lib/i386-linux-gnu/libXcursor.so.1.0.2:
/usr/lib/i386-linux-gnu/libXrandr.so.2.2.0:
6.) Workaround (use Oneiric libXrender library version):
6.1) Copy /usr/lib32/libXrender* from Oneiric to
/opt/IBM/WID62/oneiric/usr/lib32/
6.2) Make WID startup script /opt/IBM/WID62/runwid.sh with following content:
LD_LIBRARY_PATH=/opt/IBM/WID62/oneiric/usr/lib32:$LD_LIBRARY_PATH
/opt/IBM/WID62/wid.bin $*
6.3) chmod +x /opt/IBM/WID62/runwid.sh
6.4) /opt/IBM/WID62/runwid.sh
