Darker sprite colors when using gl/angle

[kolen]

I'm using gl wgpu backend (via angle, with angle feature enabled for wgpu).

wgpu = { version = "0.12.0", features = ["angle"] }

WGPU_BACKEND=gl

When I'm using this backend, sprite colors appear darker than they look in graphics editors and other programs. When compiling the same code for web, colors appear correct. I'm using 2d camera and png sprites via SpriteSheetBundle.

Is this gamma issue? Can gamma be changed?
