Release Channel

Release

macOS Version

15.6.1

Steps to Reproduce

• Set Initial window size (e.g., Width: 300pt).
• Set Initial window position (e.g., 0 right, 0 top).
• Set "Resize the window to fit video size" to Disabled.
• Open any local or online video playlist.

Expected Behavior

The video should open at 300px width and be placed in the top-right corner of the screen. When clicking another video in the playlist, the window should remain at 300px width, as it did in versions prior to v1.4.0.

Actual Behavior

The video opens at 300px width and is placed in the top-right corner of the screen. However, when clicking another video in the playlist, the window enlarges to fit the video's width, ignoring the "Resize window to fit video size: Disabled" setting.

This behavior did not occur in versions prior to v1.4.0.

Additionally, using autofit and autofit-larger in the Additional MPV options has no effect — they are not respected either.
