- GPU model, driver and version: AMD Radeon RX 6900 XT (24.30.31.03-250225a-413647C-AMD-Software-Adrenalin-Edition)
- Source of mpv: zhongfly build
- Latest known working version: unknown
- Issue started after the following happened: I removed `gpu-api=vulkan` from my mpv.conf

Reproduction Steps

In mpv.conf, set fs=yes.
Make sure you are not using gpu-api=vulkan or gpu-api=opengl (these produce the expected behaviour).
Define an auto-profile:

[no-video]
profile-desc=Starts the player without fullscreen when playing audio-only content.
profile-cond=vid == false
fs=no
autofit=600

Play an audio file.

Expected Behavior

Player starts as a small window (i.e. both fs=no and autofit=600 are applied).

Actual Behavior

Player starts in fullscreen, but the window is small after manually leaving fullscreen (i.e. fs=no is not applied, but autofit=600 is).

• Both the terminal and the log file indicate that the autoprofile has been applied, and according to the log file both fs=no and autofit=600 are applied.
• The expected behaviour is produced if the no-video profile is applied manually using mpv --profile=no-video [audio_file]
• The following auto-profile does work correctly when opening image files, regardless of the gpu-api setting:

[image]
profile-desc=Starts the player looping and maximised when displaying still images.
profile-cond=p["track_list/0/image"]
fs=no
border=yes
window-maximized=yes
loop-playlist=yes
loop-file=yes

• Tested across multiple audio files, and with lua scripts disabled (although log files provided below are with lua scripts enabled)

Log File

Problematic behaviour described above: output.txt

Expected behaviour by manually applying profile: manual-profile.txt
Expected behaviour using Vulkan: vulkan.txt
Expected behaviour using the other auto-profile described above: image-profile.txt

Sample Files

No response

I carefully read all instruction and confirm that I did the following:

• I tested with the latest mpv version to validate that the issue is not already fixed.
• 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.

Try build from #16127, also I'm curios for other regressions, because I couldn't find where SC_RESTORE fullscreen toggle is needed.

Yes, this does fix the issue. Interestingly, D3D11 still behaves differently from Vulkan using that patch, if the auto-profile is not applied when starting the player (e.g. if the player is opened on its own then the audio file dragged to it, or a video file is opened first and then an audio file added to the playlist). In this case, Vulkan correctly centres the small window after exiting fullscreen but D3D11 places it near the top left of the screen. However, if an audio file is played directly, both APIs appear to behave the same and correctly place the small window in the centre of the screen. The screen position issue is very minor, so I'm happy to consider this bug fixed if you are.
