Reproduction steps

mpv --no-config --vo=gpu-next -v -v --log-file=output.txt bbb-1920x1080-cfg02.mkv

Expected behavior

When using stats.lua page 2 to view Frame Timing the Redraw section should update every second (the same way the Fresh section updates every second).

Actual behavior

When using stats.lua page 2 to view Frame Timing the Redraw section doesn't update every second. (It does update maybe between 5 seconds to 15 seconds, each update is random interval).

Can't reproduce. I'm not sure what the stats.lua timer is but it updates roughly every second for me. Also looks like this build is one commit before 27a78276eb4b68f230e441e1baedf26f3cd66fbd so that shouldn't be related.

When you say "Can't reproduce" - did you test it on a Windows 10 machine using NVIDIA GPU playing the same video file?

I have this issue when I play any video that's 60fps, it doesn't matter if the video is a local file or a YouTube video. I believe this issue is not new, because I vaguely remember ignoring it.

[Dudemanguy]

Sorry I guess I should have been clearer. I'm on Linux (amdgpu), and I can't reproduce it with that file or any other 60fps video I have lying around.

I can't reproduce this on wayland either. Did this used to not be like this at some point? A bisect would be helpful

It was always like this. The only improved I've seen with my testing is that at the starting point (the oldest build) it wasn't updating at all, but at some point around 2023-03 it improved by updating but not frequently.

Are you pressing i or toggling it with I?

Shift+i then 2 to view Frame Timings.

Noticed the same issue on video file 480i 29.970fps (mpv --no-config --vo=gpu-next) So it's not just 60fps video files.

I don't have this issue when playing 1080p 23.976fps video files (did not use --no-config).

[Obegg]

I just tested it on 60fps video to make sure if this issue still exists after all this time and I found out that this issue still exists. The Redraw simply doesn't update.
