Created attachment 129031 [details] output from 'gdb kdenlive run' SUMMARY If I try to edit a title clip that's already been placed in the timeline kdenlive hangs. This happens regardless of threading/GPU rendering settings. Doesn't matter what I configure in kdenlive, actually (I tried changing all sorts of settings to see if I could isolate the problem). STEPS TO REPRODUCE 1. Add a video and some title clips to the timeline. 2. Edit one of those title clips. OBSERVED RESULT It hangs forever until I kill it.

Please try with the current Kdenlive AppImage version 20.08.0 to see if there are any packaging issues https://files.kde.org/kdenlive/release/ If the problem/issue doesn't occur when using the AppImage, then it's your configuration or packaging. WARNING: Version 20.08.0 has a new project type that is not backwards compatible... so you won't be able to use older versions to open new files.
