Linear gradient not working as expected on iPad

Hello everyone, hope you guys doing well on webflow ! If you have some time to share, I would appreciate the help on this.

All my linear gradients (all from black to transparent) are showing the transparent part weirdly on iPad. You’ll understand better what i mean with these screenshot.

Here my linear gradient, a very simple one. The color of my background (#15150e) to transparent (#000000) :

As you can see, the transparent part isn’t transparent at all on iPad :

But at this place, everything seems to work “nicely”, the radial gradient and even the bottom linear gradient is working. There is no difference between all these gradients…

Thanks for any help
