Upon further checks, it appears that I can consistently crash the application by simply accessing the properties of one of the clips. The issue appears to be somewhat related to Wayland. When I switched to Xorg, the crashing stopped. I'm seeing what I believe is the same bug. I see it both with the Mate desktop and also with Gnome-xorg. All that is needed to trigger the bug is:
1. Start a new project.
2. Drag a video (a short, 40 second one will do) from the "Recent" panel into the "Playlist" panel.
3. Double-click on the video in the Playlist panel and allow it to play.
After about 90 seconds (possibly well after the video has finished playing), the SEGFAULT occurs.
Thread 59 "Thread (pooled)" received signal SIGSEGV, Segmentation fault.

The "Linux portable tar" version of Shotcut 25.05.11 downloaded from www.shotcut.org seems to work just fine in my Mate desktop, so it appears the problem is not upstream. |
