Same here. Same version of aegisub. But Mint Mate 20. Kernel: 5.4.0-42-generic I load any .mp4 file to add subtitles. I play the video file. While the video itself plays with correct speed the sound track plays much faster. 3 times as fast? Because the sound track finishes while the video track is around 1/3 of the complete video file.
Reproduce: Just install it: "sudo apt install aegisub" Run: aegisub-3.2 Open any .mp4 video file. Play the file. (Subs not even added. But even with added subs - no change) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1714074 Title: Aegisub plays back at 2x speed after changing focus to different program To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/aegisub/+bug/1714074/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
