it seems some of the icons are either not installed or not found. They should be in ${DATA_INSTALL_DIR}/kolourpaint/icons e.g. here on openSUSE they are in /usr/share/kolourpaint/icons/ Try using a different icon theme and see if that changes things

"Try using a different icon theme and see if that changes things" How to? Is this a KDE or kolourpaint setting? Thanks, -Reed

In Qt's documentation I read: "Qt will make use of GTK's icon-theme.cache if present to speed up the lookup. These caches can be generated using gtk-update-icon-cache: https://developer.gnome.org/gtk3/stable/gtk-update-icon-cache.html." Maybe this cache update is somehow missing after the installation. Can you check if - it works automagically after a re-login or - try running gtk-update-icon-cache manually

I built kolourpaint for GNU/Linux 3.2.0, with debug_info, not stripped. On startup under gdb I now see: Icon theme "breeze" not found. Toolbox icons still don't render (render as text). Right mouse button select of toolbar settings, text position, icons only - has no effect. exit kolourpaint I install breeze-icon-theme & gnome-tweaks sudo apt install breeze-icon-theme sudo apt update && sudo apt install gnome-tweaks I use gnome-tweaks to select the breeze icon theme (yuk). restart kolourpaint under gdb. Note 'Icon theme "breeze" not found.' message no longer printing. Toolbox icons are rendered correctly.
