After running Evolution for about 5 minutes I get this memory leak for memory allocated in pixman, used by cairo, through gtk. One of these is responsible :) This is for: cairo-1.12.8-1.fc18.x86_64 pixman-0.26.2-5.fc18.x86_64 gtk3-3.6.1-1.fc18.x86_64 Valgrind snap: 1,672,800 bytes in 6,150 blocks are definitely lost in loss record 39,956 of 39,961 at 0x4A0883C: malloc (vg_replace_malloc.c:270) by 0x3C95E4306A: _pixman_image_allocate (pixman-image.c:184) by 0x3C95E1C7A2: pixman_image_create_bits (pixman-bits-image.c:1501) by 0x7C27E69: _cairo_xlib_shm_surface_create.isra.11 (cairo-xlib-surface-shm.c:768) by 0x7C28746: _cairo_xlib_surface_create_shm (cairo-xlib-surface-shm.c:1085) by 0x7C287E9: _cairo_xlib_surface_create_similar_shm (cairo-xlib-surface-shm.c:1112) by 0x7C233A0: _cairo_xlib_source_create_for_pattern (cairo-xlib-source.c:955) by 0x7C094F5: clip_and_composite_boxes (cairo-traps-compositor.c:1272) by 0x7C09ECA: _cairo_traps_compositor_paint (cairo-traps-compositor.c:2036) by 0x7BB6FC0: _cairo_compositor_paint (cairo-compositor.c:65) by 0x7BF77B0: _cairo_surface_paint (cairo-surface.c:2006) by 0x7BFC505: _cairo_surface_offset_paint (cairo-surface-offset.c:85) by 0x7BFD9BE: _cairo_surface_subsurface_paint (cairo-surface-subsurface.c:122) by 0x7BF77B0: _cairo_surface_paint (cairo-surface.c:2006) by 0x7BBE84B: _cairo_gstate_paint (cairo-gstate.c:1067) by 0x7BB1B56: cairo_paint (cairo.c:1999) by 0x3C9A860D34: gtk_theming_engine_render_icon (gtkthemingengine.c:2809) by 0x3C9A81B27D: gtk_render_icon (gtkstylecontext.c:4325) by 0x3C9A75F4E9: _gtk_icon_helper_draw (gtkiconhelper.c:589) by 0x3C9A76FD17: gtk_image_draw (gtkimage.c:1416) by 0x3C9A78EB2E: _gtk_marshal_BOOLEAN__BOXEDv (gtkmarshalers.c:130) by 0x3C9A8BA01D: gtk_widget_draw_marshallerv (gtkwidget.c:851) by 0x3C88A0FB0A: _g_closure_invoke_va (gclosure.c:840) by 0x3C88A283A7: g_signal_emit_valist (gsignal.c:3211) by 0x3C88A28DE1: g_signal_emit (gsignal.c:3356) by 0x3C9A8BD4FB: _gtk_widget_draw_internal (gtkwidget.c:5752) by 0x3C9A6FB482: gtk_container_propagate_draw (gtkcontainer.c:3394) by 0x3C9A6B53D9: gtk_box_forall (gtkbox.c:1865) by 0x3C9A6F9E6B: gtk_container_draw (gtkcontainer.c:3258) by 0x3C9A78EB2E: _gtk_marshal_BOOLEAN__BOXEDv (gtkmarshalers.c:130) by 0x3C9A8BA01D: gtk_widget_draw_marshallerv (gtkwidget.c:851) by 0x3C88A0FB0A: _g_closure_invoke_va (gclosure.c:840) by 0x3C88A283A7: g_signal_emit_valist (gsignal.c:3211) by 0x3C88A28DE1: g_signal_emit (gsignal.c:3356) by 0x3C9A8BD4FB: _gtk_widget_draw_internal (gtkwidget.c:5752) by 0x3C9A6FB482: gtk_container_propagate_draw (gtkcontainer.c:3394) by 0x3C9A6F9E6B: gtk_container_draw (gtkcontainer.c:3258) by 0x3C9A78EB2E: _gtk_marshal_BOOLEAN__BOXEDv (gtkmarshalers.c:130) by 0x3C9A8BA01D: gtk_widget_draw_marshallerv (gtkwidget.c:851) by 0x3C88A0FB0A: _g_closure_invoke_va (gclosure.c:840) by 0x3C88A283A7: g_signal_emit_valist (gsignal.c:3211) by 0x3C88A28DE1: g_signal_emit (gsignal.c:3356) by 0x3C9A8BD4FB: _gtk_widget_draw_internal (gtkwidget.c:5752) by 0x3C9A6FB482: gtk_container_propagate_draw (gtkcontainer.c:3394) by 0x3C9A6F9E6B: gtk_container_draw (gtkcontainer.c:3258) by 0x3C9A6BF176: gtk_button_draw (gtkbutton.c:1766) by 0x3C9A78EB2E: _gtk_marshal_BOOLEAN__BOXEDv (gtkmarshalers.c:130) by 0x3C9A8BA01D: gtk_widget_draw_marshallerv (gtkwidget.c:851) by 0x3C88A0FB0A: _g_closure_invoke_va (gclosure.c:840) by 0x3C88A283A7: g_signal_emit_valist (gsignal.c:3211)
Just in case, this is fallback mode, not a gnome-shell.
