Created attachment 188178 [details] Blurry icons even when SVG files are available SUMMARY Blurry icons when using some SVG icon theme STEPS TO REPRODUCE 1. Install an SVG icon theme, e.g., Gartoon Redux - The package is available in Ubuntu 25.10 repo, package name: gnome-icon-theme-gartoon-redux 2. Select the icon theme in System Settings > Colors & Themes > Icons 3. Launch Dolphin and zoom in (increase icon size) OBSERVED RESULT Icons should be smooth EXPECTED RESULT Icons are blurry. See the attachment blurry_icons.png SOFTWARE/OS VERSIONS Operating System: Ubuntu 13 KDE Plasma Version: 6.4.5 KDE Frameworks Version: 6.17.0 Qt Version: 6.9.2 Kernel Version: 6.17.0-7-generic (64-bit) Graphics Platform: Wayland ADDITIONAL INFORMATION The relevant code is in kiconthemes/src/kicontheme.cpp - KIconTheme::iconPathByName() returns the first matching icon matching a name - The extensions to be considered are .png, .svgz, .sgv, .xpm in that order, as defined by mExtensions - For example, for `inode-directory`, there are two matching files: + /usr/share/icons/GartoonRedux/32x32/mimetypes/inode-directory.png + /usr/share/icons/GartoonRedux/scalable/mimetypes/inode-directory.svg - The first file is selected even though the second one is better To confirm the analysis, I re-ordered the extensions to prioritize .svg over .png files and the icons are now smooth.
