openshot 2.4.3 under GuxSD works in an off hand way Note exactly this: have lag when pull image from files list to a timeline - cursor just becomes circle and program stops for 15 seconds. and after that openshot can crash or can also perform image addition to a timeline starts playing when cursor is on the start so ugly: waiting for 10 seconds after pressing play and breaks audio in start time sometimes it stops when move or edit images length on a timeline The worst bug is waiting 5secs and sound breaking when click 'play' on start postition. I think should examine and improve openshot from guix repository.
