Reproduction Steps

idk what the source of the problem is, but i use this config file, and when commenting
scale-antiring = 0.4
the problem goes away, but when using mpv --no-config --scale-antiring=0.4 the problem is also resolved, so i don't really know what the source of the problem is.

Expected Behavior

correct video playback

Actual Behavior

Log File

output.txt

Sample Files

i can't
this is the file i'm having issues with (torrent)
the same problem with this video

I carefully read all instruction and confirm that I did the following:

• I tested with the latest mpv version to validate that the issue is not already fixed.
• 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.

Start by comparing the linked configuration with the minimal mpv --no-config --scale-antiring=0.4 invocation, then inspect output.txt while reproducing the artifacts on the reported Windows and Intel HD Graphics 5500 setup. Done means the source of the rendering difference is identified and playback no longer shows the reported artifacts under the relevant configuration.
