Package: libgtk2.0-0 Version: 2.20.1-1 Severity: important Dear Debian developers,
Because of a bug in a video driver, I had to disable Xorg's RENDER extension. As a result, the performance of GTK decreased significantly, and the applications on top of GTK, including Firefox and Eclipse, are almost unusable: gtkperf with RENDER: 11s gtkperf without RENDER: 40s On the contrary, applications on top of QT perfectly resist disabling RENDER. --Martin Additional information: * It seems that GTK uses libxft when RENDER is present and libfreetype otherwise. * "pango-view --backend=ft2" is as slow as with RENDER disabled, the other pango backends are always fast (with and without RENDER). * I did not find in the documentation a way to configure libgtk so that it does not use at all libfreetype as Pango backend. -- System Information: Debian Release: 5.0 APT prefers testing APT policy: (990, 'testing') Architecture: i386 (i686) Kernel: Linux 2.6.28-15-generic (SMP w/2 CPU cores) Locale: LANG=en_US.ISO-8859-1, LC_CTYPE=en_US.ISO-8859-1 (charmap=ISO-8859-1) Shell: /bin/sh linked to /bin/bash Versions of packages libgtk2.0-0 depends on: ii libatk1.0-0 1.30.0-1 The ATK accessibility toolkit ii libc6 2.10.2-9 Embedded GNU C Library: Shared lib ii libcairo2 1.8.10-4 The Cairo 2D vector graphics libra ii libcups2 1.4.3-1 Common UNIX Printing System(tm) - ii libfontconfig1 2.8.0-2.1 generic font configuration library ii libfreetype6 2.3.11-1 FreeType 2 font engine, shared lib ii libglib2.0-0 2.24.0-1 The GLib library of C routines ii libgnutls26 2.8.3-3 the GNU TLS library - runtime libr ii libgssapi-krb5-2 1.8.1+dfsg-2 MIT Kerberos runtime libraries - k ii libgtk2.0-common 2.20.1-1 Common files for the GTK+ graphica ii libjasper1 1.900.1-5.1 The JasPer JPEG-2000 runtime libra ii libjpeg62 6b-16.1 The Independent JPEG Group's JPEG ii libpango1.0-0 1.28.0-1 Layout and rendering of internatio ii libpng12-0 1.2.43-1 PNG library - runtime ii libtiff4 3.8.2-11 Tag Image File Format (TIFF) libra ii libx11-6 2:1.3.3-3 X11 client-side library ii libxcomposite1 1:0.4.0-3 X11 Composite extension library ii libxcursor1 1:1.1.9-1 X cursor management library ii libxdamage1 1:1.1.1-4 X11 damaged region extension libra ii libxext6 2:1.1.1-3 X11 miscellaneous extension librar ii libxfixes3 1:4.0.3-2 X11 miscellaneous 'fixes' extensio ii libxi6 2:1.3-4 X11 Input extension library ii libxinerama1 2:1.0.3-2 X11 Xinerama extension library ii libxrandr2 2:1.3.0-3 X11 RandR extension library ii libxrender1 1:0.9.5-2 X Rendering Extension client libra ii shared-mime-info 0.70-1 FreeDesktop.org shared MIME databa ii zlib1g 1:1.2.3.4.dfsg-3 compression library - runtime -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
