--- Comment #1 from [email protected] --- I've found out after running callgrind, that function Plasma::SvgRectsCache::loadImageFromCache is called over 50000 times when textual list for a group of 50 windows is displayed. I've logged every filename passed to this function after start of plasmashell, creating group of 50 windows and displaying it (once or just few times). One of images was loaded over 46000 times. $ cat plasma.log | awk '{ print $12 }' | sort | uniq -c | sort -h -r 46277 /usr/share/kf5/plasma/desktoptheme/default/widgets/button.svgz, 3150 /usr/share/kf5/plasma/desktoptheme/default/icons/media.svgz, 1052 /usr/share/kf5/plasma/desktoptheme/default/widgets/viewitem.svgz, 1052 /usr/share/kf5/plasma/desktoptheme/default/icons/window.svgz, 1051 /usr/share/icons/breeze/actions/32/window-close.svg, 1050 /usr/share/icons/breeze/actions/32/media-skip-forward.svg, 1050 /usr/share/icons/breeze/actions/32/media-skip-backward.svg, 1050 /usr/share/icons/breeze/actions/32/media-playback-start.svg, 266 /usr/share/kf5/plasma/desktoptheme/default/widgets/tasks.svgz, 264 /usr/share/icons/breeze/apps/32/utilities-terminal.svg, 57 /usr/share/icons/breeze/actions/22/media-skip-forward.svg, 57 /usr/share/icons/breeze/actions/22/media-skip-backward.svg, 57 /usr/share/icons/breeze/actions/22/media-playback-start.svg, 57 /usr/share/icons/breeze/actions/16/window-close.svg, 25 /usr/share/kf5/plasma/desktoptheme/default/widgets/scrollbar.svgz, 12 /usr/share/icons/breeze/status/22/update-none.svg, 11 /usr/share/kf5/plasma/desktoptheme/default/icons/system.svgz, 9 /usr/share/kf5/plasma/desktoptheme/default/dialogs/background.svgz, 6 /usr/share/kf5/plasma/desktoptheme/default/icons/korgac.svgz, 5 /usr/share/kf5/plasma/desktoptheme/default/widgets/scrollwidget.svgz, 4 /usr/share/kf5/plasma/desktoptheme/default/widgets/tooltip.svgz, 4 /usr/share/kf5/plasma/desktoptheme/default/widgets/tabbar.svgz, 4 /usr/share/icons/breeze/actions/16/view-history.svg, 3 /usr/share/kf5/plasma/desktoptheme/default/widgets/lineedit.svgz, 3 /usr/share/kf5/plasma/desktoptheme/default/widgets/busywidget.svgz, 3 /usr/share/kf5/plasma/desktoptheme/default/opaque/widgets/tooltip.svgz, 2 /usr/share/kf5/plasma/desktoptheme/default/widgets/plasmoidheading.svgz, 2 /usr/share/kf5/plasma/desktoptheme/default/widgets/panel-background.svgz, 2 /usr/share/kf5/plasma/desktoptheme/default/widgets/line.svgz, 2 /usr/share/kf5/plasma/desktoptheme/default/widgets/arrows.svgz, 2 /usr/share/kf5/plasma/desktoptheme/default/icons/user.svgz, 2 /usr/share/kf5/plasma/desktoptheme/default/icons/preferences.svgz, 2 /usr/share/icons/breeze/preferences/32/preferences-desktop.svg, 2 /usr/share/icons/breeze/categories/32/applications-system.svg, 2 /usr/share/icons/breeze/categories/32/applications-office.svg, 2 /usr/share/icons/breeze/categories/32/applications-network.svg, 2 /usr/share/icons/breeze/categories/32/applications-multimedia.svg, 2 /usr/share/icons/breeze/categories/32/applications-graphics.svg, 2 /usr/share/icons/breeze/categories/32/applications-development.svg, 2 /usr/share/icons/breeze/apps/48/utilities-terminal.svg, 2 /usr/share/icons/breeze/apps/48/telepathy-kde.svg, 2 /usr/share/icons/breeze/apps/32/preferences-system.svg, 2 /usr/share/icons/breeze/apps/32/hwinfo.svg, 2 /usr/share/icons/breeze/actions/16/system-log-out.svg, 1 /usr/share/kf5/plasma/desktoptheme/default/widgets/pager.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/widgets/listitem.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/widgets/frame.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/widgets/configuration-icons.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/widgets/background.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/widgets/action-overlays.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/icons/start.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/icons/printer.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/icons/notification.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/icons/network.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/icons/list.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/icons/klipper.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/icons/kdeconnect.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/icons/input.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/icons/go.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/icons/edit.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/icons/device.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/icons/configure.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/icons/battery.svgz, 1 /usr/share/kf5/plasma/desktoptheme/default/icons/audio.svgz, 1 /usr/share/icons/breeze/status/22/redshift-status-off.svg, 1 /usr/share/icons/breeze/preferences/32/preferences-desktop-wallpaper.svg, 1 /usr/share/icons/breeze/places/32/folder-favorites.svg, 1 /usr/share/icons/breeze/actions/22/window-close.svg, 1 /usr/share/icons/breeze/actions/22/notifications-disabled.svg, 1 /usr/share/icons/breeze/actions/22/meeting-attending.svg, 1 /usr/share/icons/breeze/actions/22/edit-clear-locationbar-rtl.svg, 1 /usr/share/icons/breeze/actions/22/activities.svg, -- You are receiving this mail because: You are watching all bug changes.
