Just upgraded from 25.08.0 to 25.12.0, and now Kdenlive won’t open the main window.
I’m running Debian Sid (unstable) and Hyprland 0.52.1 (i.e. Wayland), and am using the Kdenlive build on deb-multimedia . org which, in my experience, is usually the least problematic.
Upon launch, the new startup window appears, listing recently opened projects. Upon selecting a project, the load progress popup appears, then both windows disappear, and the main window never appears. ps shows the program is running. Running Kdenlive from the command line prints out a ton of status and progress messages, but nothing obviously stands out as the culprit. Running kdenlive -–no-welcome doesn’t help (indeed, in this mode, pressing CTRL-C has no effect; you have to resort to CTRL-\ to kill the program).
This is more annoying than usual, as I was in the middle of working on a personal project. Rolling back to 25.08.0 isn’t (easily) possible, as deb-multimedia only keeps the most recent version. I have not yet tried purging the config files. I’m about to try rebooting, as other system libraries got updated as well.
Suggestions welcome.
