Reproduction Steps

hwdec=auto-safe (though I believe any form of hwdec is the same) causes weird frame corruption as pictured. Tested exclusively on vulkan. I am not sure what GPU it is using on this laptop.

The file being played is a BlueRay of the anime movie "A Wind Named Amnesia".

Expected Behavior

Actual Behavior

Log File

logfile.txt

Sample Files

mpv.zip

My config folder is attached, but most of it is irrelevant. Only thing that matters as far as I can tell is that hwdec is on. Rest is attached a precaution. I don't use shaders but I have them downloaded.

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.

Start by reproducing the corruption with the attached mpv.zip sample, configuration, and logfile.txt using Vulkan hardware decoding, then determine which GPU and hardware-decoding path is active. Done means the supplied video renders without corruption with hardware decoding enabled, with a regression test or documented reproduction result if the affected path permits one.
