This happened on the previous version of SMP but it still happens after I updated to the latest version on Manjaro :
Version: 21.1.0 (revision 9475)
Using Qt 5.15.2 (compiled with Qt 5.15.2)
Using MPV 0.33.0
This is the log for that session : https://0x0.st/-KPf.log
Note from the image that standalone mpv displays the video properly, which to me makes this all the more mysterious.
If this is not a bug but a misconfiguration on my end, can you point to me where I made that mistake? Thank you.
