Created attachment 182083 [details] Showcase of the bug. SUMMARY When using KDE File Picker to save files, it takes a while before it filters out the files when `File Type` is set. STEPS TO REPRODUCE 1. Have 1 or more files with the same file extension (.webp, for example) in `Downloads` folder. 2. Make sure the File Picker in Firefox/Chromium loads the `Downloads` folder first. 3. In Firefox/Chromium, download a file that has a different extension (.png, for example). OBSERVED RESULT The file picker is slow to filter the files. EXPECTED RESULT Near instantaneous results, it's currently the same if there's 1 or 10 other files that need to be filtered. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora 42 KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.14.0 Qt Version: 6.9.0 ADDITIONAL INFORMATION - The speed between filtering 1 or 10 files is the same. - Only the first folder opened in KDE File Picker is slow to filter, other folders are filtered instantly.
Hmm, it's instantaneous for me, also on Fedora 42, but with all KDE software built from source from today's git master.
I can also reproduce it on Fedora Rawhide and KDE Neon Unstable. On these two distros I had to change `widget.use-xdg-desktop-portal.file-picker` to 1 in Firefox so that it would use the KDE File Picker. Fedora Rawhide (Fedora-Rawhide-20250608.n.0) KDE Plasma Version: 6.3.91 KDE Frameworks Version: 6.14.0 QT Version 6.9.0 Kernel: 6.16.0 kdialog: 25.04.2 xdg-desktop-portal-kde: 6.3.91 KDE Neon Unstable (neon-unstable-20250608-1147) KDE Plasma Version: 6.4.80 KDE Frameworks Version: 6.15.0 QT Version: 6.9.0 Kernel: 6.11.0 kdialog: 25.04.2 xdg-desktop-portal-kde: 6.3.5
I can reproduce what's shown in the video - a brief flash of the unfiltered contents as the file picker window loads. For the reporter, could you please also add your full Info Center/kinfo details, including graphics card info, in case it's relevant? (Mine are below as an example) Thanks!
