- Issue started after the following happened:Tried to drag a short video's progress bar around.

Reproduction Steps

Open a short video and drag the progress bar around.

https://github.com/user-attachments/assets/1642c8a3-03bf-4b34-aa0f-209fa01768cd

Expected Behavior

The progress bar should behave normally.

Actual Behavior

The progress bar jitters intensely.

Log File

output.txt

Sample Files

Any short video has this issue. Here's one.

https://github.com/user-attachments/assets/eabdfed5-ed4c-4e30-b40c-2d272441e564

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.

Reproduce the issue by opening the attached short video and dragging the progress bar, using the provided mpv v0.41.0 environment and output.txt log. Compare the observed behavior with the expected normal progress-bar interaction; the work is done when dragging short videos no longer causes intense jitter.
