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... -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libxrender in Ubuntu. https://bugs.launchpad.net/bugs/1033253 Title: WebSphere Integration Developer 6.2 (Eclipse 3.4) - BPEL editor is slow for large windows Status in “libxrender” package in Ubuntu: New Bug description: 1.) lsb_release -rd Description: Ubuntu 12.04.1 LTS Release: 12.04 2.) apt-cache policy libXrender1 libxrender1: Installed: 1:0.9.6-2build1 Candidate: 1:0.9.6-2build1 Version table: *** 1:0.9.6-2build1 0 500 http://archive.ubuntu.com/ubuntu/ precise/main amd64 Packages 100 /var/lib/dpkg/status apt-cache policy libXrender1:i386 libxrender1:i386: Installed: 1:0.9.6-2build1 Candidate: 1:0.9.6-2build1 Version table: *** 1:0.9.6-2build1 0 500 http://archive.ubuntu.com/ubuntu/ precise/main i386 Packages 100 /var/lib/dpkg/status 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 http://lino.ubuntuupdates.org/pm/libxrender precise main base 1:0.9.6-2build1 oneiric main base 1:0.9.6-2 Change Log: Version: 1:0.9.6-2build1 2012-03-02 07:04:57 UTC libxrender (1:0.9.6-2build1) precise; urgency=low * No-change rebuild against current pkgbinarymangler to fix broken md5sums.
