vo_gpu-next: Scaled subtitles appearing more transparent when resized.

[TemAccount]

Important Information

Provide following Information:

• mpv 0.34.0-265-g305332f8a0
• Windows 11 22H2 (OS Build 22598.1)
• Source of the mpv binary

Reproduction steps

mpv.conf

vo=gpu-next
profile=gpu-hq

• Launch a 1080p video with .ass subtitles.
• Go fullscreen, scaling the subtitles to 2560x1440
• Subtitle sign goes transparent.

Expected behavior

Subtitles to not get more transparent when scaling / resizing larger. To have similar behavior to current default vo=gpu.

Actual behavior

Subtitle sign becomes transparent.

With vo=gpu-next set.

No vo=gpu-next set, using the default vo=gpu.

Displaying without scaling the video/subs larger (no fullscreen) shows the subtitles fine. Similarly, removing profile=gpu-hq with vo=gpu-next present while going fullscreen seems to fix the problem. So perhaps indication custom settings / scalers set don't play nicely with resizing subtitles on gpu-next.

Looks like the thicker/deeper border/shadow.

I can't reproduce this. Is it still an issue?

[Dudemanguy]

I cannot reproduce either + this is old so I will assume it has been fixed. Feel free to reopen if this is not the case.
