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).

Log file

output.txt

Start with stats.lua page 2 and reproduce the issue using the provided mpv command, sample video, and output log. Compare the Redraw and Fresh frame-timing updates while playing the 60fps file; done means Redraw updates every second as expected.
