STEPS TO REPRODUCE 1. open Dolphin 2. right-click on a large file (I used a 1 GiB video file in my tests), hover over 'Compress' and choose the option to create an archive of any format below: tar.gz tar tar.bz2 tar.lzma tar.xz tar.Z tar.lz4 tar.lz tar.zst 3. OBSERVED RESULT while the archive is created, Plasma shows a notification with a unhelpful ping-pong 'progress' bar EXPECTED RESULT notification with an helpful progress bar SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.25.90 KDE Frameworks Version: 5.98.0 Qt Version: 5.15.6 Graphics Platform: Wayland ADDITIONAL INFORMATION Plasma shows a notification with an helpful progress bar as expected if I compress a folder containing files instead of a single file.
Created attachment 152204 [details] Video showing the unhelpful ping-pong 'progress' bar
Can also reproduce by creating a .arj archive.
This seems to be independent of the choosen format and it also happens if you create an archive via. Ark itself - not only via context menu. The problem with progress bars is how you calculate them. In this case ark uses the file count, but this is cumbersome with big files or a mixed set with small and big files. File size might be a better option, but could be misleading if lots of small files slow down the process. - At least for a single file operation the filesize would be helpful - A data transfer rate would make a good addition - One good solution might be to show two progress bars: current file and overall progress
