When the device screen rotation direction changes, the saturation or color gamut decreases.

Environment

• OS: MacOS 15.3
• **Scrcpy version:**3.1
• Installation method: brew
• **Device model:**Macbook Pro 14' 2023
• Android version: 15

Describe the bug

When the device screen rotation direction changes, the color of the scrcpy changes: the saturation or color gamut decreases, making the image look gray. By comparing it with the newly opened window, the problem can be clearly seen
This issue occurs on MacOS but not on Windows.

If this happens only on macOS, this is probably a SDL issue.

If you record: scrcpy --record=file.mp4 then play the file, do you have the same problem?

[TBCJames]

The problem did not occur in the recorded file, but only appears in the window.

[rom1v]

And this happens after a rotation, regardless of the initial orientation?

What about yet another rotation? Does it work again?

[TBCJames]

Yes, regardless of the initial orientation, this problem occurs as long as there is a rotation. The problem still exists with another rotation and will not get worse or restore.

Check your SDL version in the output of scrcpy -v, and please report an issue here: https://github.com/libsdl-org/SDL/

It seems that further textures created by SDL_CreateTexture() behave differently as the first one, only on macOS:

scrcpy/app/src/display.c

Lines 130 to 132 in 0ba9d35

	SDL_Texture *texture = SDL_CreateTexture(renderer, SDL_PIXELFORMAT_YV12,
	SDL_TEXTUREACCESS_STREAMING,
	size.width, size.height);
