Weird yellow background when using Glur on macOS about glur HOT 3 OPEN

also, this is such a great use of this effect. are you using it to make app previews?

from glur.

Yeah that's the plan! I saw Glur, and I was like, this is such a cool effect to have in app screenshots, I have it integrate it haha.

Let me take a look at what is included in the item I'm blurring. Without revealing too much about the code I'm using to create the device frame, I'm using the following modifiers before applying the Glur effect:

.opacity
Group to handle if conditions on modifiers
.shadow
.overlay
.blendMode
.onDrop
.simultaneousGesture
.onTapGesture
.scaleEffect

I'm drawing the device at full size (somewhere around 1242 x 2688), then using scaleEffect to scale it down in the app, before applying Glur. I was having trouble getting Glur to work before the scale effect, but moving it to after seemed to help. I still have problems for certain large devices even after the scale, like iPads.

Here's my View extension that leverages Group:

public extension View {

    func `if`<Content: View>(_ condition: Bool, content: (Self) -> Content) -> some View {
        Group {
            if condition {
                content(self)
            } else {
                self
            }
        }
    }
}

from glur.

hey!

I think I know what this is. when SwiftUI isn't able to rasterize a view (such as through .drawingGroup) it displays a red prohibited icon over a yellow background.

this might be what's happening here, as your background view might not work with .drawingGroup on Mac specifically... is it just a gradient or is there something else?
