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

   oneiric main base 1:0.9.6-2

           -- Martin Pitt Wed, 29 Feb 2012 17:58:51 +0100

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
     /opt/IBM/WID62/configuration/org.eclipse.osgi/bundles/2282/1/.cp/libswt-atk-gtk-3453.so:
     /opt/IBM/WID62/configuration/org.eclipse.osgi/bundles/2282/1/.cp/libswt-cairo-gtk-3453.so:

     /usr/lib/i386-linux-gnu/libgtk-x11-2.0.so.0.2400.10:

     /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

[Rostislav Stříbrný (rstribrn)]

No (relevant) stdout/stderr errors were logged after Eclipse was started.
That's also the case for .metadata/.log log file in Eclipse's workspace.

[Rostislav Stříbrný (rstribrn)]

I've just checked that the bug is also present in latest Ubuntu: 12.10 Quantal Quetzal.
Since nobody has been assigned to this bug I wonder, how to proceed...

I seems to me like a simple compile-time problem or something...

[Rostislav Stříbrný (rstribrn)]

Problem still valid, I'm about to ugprade to 13.04 soon. So I will report if the bug will be still there (or more interestingly, whether the workaround would still work)...:-)

[Rostislav Stříbrný (rstribrn)]

I've just upgraded from Ubuntu 12.10 to Ubuntu 13.04 during the weekend.
1.) The problem with libxrender library is STILL valid.
2.) Moreover, the workaround with oneiric's libxrender library version no longer works (entire X server crashes after few clicks in WebSphere Integration Studio when BPEL is opened).

So I've to find some other solution. :-(((

I still don't have a solution but here are my latest findings about this issue:

6.) SOLUTION - WORKAROUND 2:
 After applying this workaround, BPEL rendering is fast again (in WID 6.2) and WID doesn't crash anymore.

    Note: Workaround no. 1 used libxrender.so only. Now more (dependent) libraries are also needed.

6.1) This patch is probably NOT needed:
 Download: eclipse.platform.swt.binaries-3453i.zip
  URL: http://git.eclipse.org/c/platform/eclipse.platform.swt.binaries.git/

 Modify files in /opt/IBM/SDPShared/plugins:
  org.eclipse.swt_3.4.2.v3453a.jar
   - Delete all files in META-INF except MANIFEST.MF
   - Remove all signature related tags (SHA-1) from META-INF/MANIFEST.MF
  org.eclipse.swt.gtk.linux.x86_3.4.1.v3453a.jar
   - Delete all files in META-INF except MANIFEST.MF
   - Remove all signature related tags (SHA-1) from META-INF/MANIFEST.MF
   - Copy new *.so files from eclipse.platform.swt.binaries-3453i.zip
    Path in ZIP: eclipse.platform.swt.binaries-3453i/bundles/org.eclipse.swt.gtk.linux.x86/
     to root of org.eclipse.swt.gtk.linux.x86_3.4.1.v3453a.jar

6.2) Use older library version (from oneiric = Ubuntu 11.10) for WID 6.2

export LD_LIBRARY_PATH=/opt/IBM/WID62/__WID_problem/oneiric/usr/lib32:$LD_LIBRARY_PATH
