- Issue started after the following happened: Play a media

Reproduction Steps

Set --geometry, move the window and play a media.

Expected Behavior

Keep mpv window position even when the --geometry options is used.

Actual Behavior

I set a position with --geometry, but if I move the window and play a media, the window go back to it's default position.
I tried --force-window-position but it's same.

The issue appears only if --geometry is used, does not happen on v0.39.0.

Log File

mpv --no-config --force-window --idle --geometry=+50%+50% --log-file=mpv_log.txt --gpu-debug
Then moved the window, played a FLAC file and left.

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.

So this is different behavior from before, but at the same time it's more consistent. Previously, setting --geometry would resize the window on a new file. If anything, the position being ignored in the case of setting xy coordinates was a bug. I'm not sure what currently happens on other platforms though.

If you don't want it to do that, you can of course just clear the --geometry option value.

I'm not sure what currently happens on other platforms though.

FYI, I refactored window sizing/positioning on Windows. I still have one or two corner cases to fix I think, maybe will have time too look at this in few days. There were some bugs in common code too. I didn't change the actual geometry handling though, but during testing noticed that it is inconsistent with say autofit, but I don't have much detail, because this would be my next step to look at the common code.
