- Issue started after the following happened:Tried to skim through a video at high speed, paused it, went back to the normal speed, then played the video.
Reproduction Steps

Increase a video's speed to 10, play it a bit, pause it, reduce the speed to 1, play it.

Expected Behavior

The video to play at normal speed from the frame it is paused at.

Actual Behavior

The video jumps a few seconds ahead, then it plays normally from there.

I carefully read all instruction and confirm that I did the following:
  • I tested and confirmed that the issue exists with the latest release version or newer.
  • I provided all required information including system and mpv version.
  • I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
  • I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
  • I attached the full, untruncated log file.
  • I attached the backtrace in the case of a crash.
