Doesn't autofit on opening video
On Windows 10, baka-mplayer will not autofit the video to 100% the player opens 100% of screen height and does not match the video height. Setting the player to manually auto-fit:100 after the video is opened works fine.
@Flat just confirming you have autofit enabled in the preferences. I may have experienced this myself though with files that are bigger in height than in width.
@u8sand Autofit is indeed enabled and this happens with videos that are wide screen as well. as shown here.

@Flat this seems to only happen to me in hide all controls mode (and it seems to be happening because they playlist is open when it fits then it closes). Can you confirm that this is indeed what is happening on your side?
Hide all controls mode is not active for me and is set to false in the ini.
@u8sand After some more looking into it looks like this bug is only present when the playlist window opens first.
