mpv 0.19.0-git-ef2d6ed, Windows
It scales 2x when windowed and 1x when full screen.
It scales correctly the first time (when opening a file windowed), but later it mostly reverts to default scaling when windowed. Also when full screen it often scales incorrectly (2x).
It's not a big deal for me, because I eventually switched to osc-vidscale=no, but anyway.
So what does "later" mean? When you resize the window manually?
Ah, sorry. I meant when I go fullscreen and windowed several times (pressing F, for example).
This is happening to me with the Sourceforge builds (haven't check the official builds, but I did compiled it myself and updated it to the last version and it worked fine)
https://i.lithi.io/2DA2h.webm - sourceforge
https://i.lithi.io/ESmD.webm - compiled with mingw(it happens here once when I go fullscreen)
https://i.lithi.io/6tlkv.txt - log.txt (sourcefoge)
https://i.lithi.io/7tyj.conf - mpv.conf
Compare to him though, I am using osc-vidscale=no and it still happens.
