Also, the default canvas background is white, but when I increase the size of a desktop window (so not a problem on web), the new space is rendered with a black background. I can avoid it by filling the canvas with white. Is this intended behavior?

[Nick]

i haven’t seen this behavior before. it sounds like a bug. will also investigate.

[Nick]

what platform do you see this on? i can’t repro on Mac.

[Alessandro Marcolini]

I'm having this issue on windows. It could also be the way I'm interacting with the canvas. I'm not painting the canvas black at all. Could canvas.clear() be causing the issue?

[Nick]

it might. clear is actually never needed. try removing and let me know.

[Alessandro Marcolini]

Yup! That fixed it 🤦

[Nick]

how are you using it? it’s no longer needed b/c the graphics surface implementations do it automatically at the tart of each new render.

[Alessandro Marcolini]

I had it at the beginning of render . I don't remember why I put it there in the first place.

[Nick]

clear should go to transparent. but this may go to black because Doodle’s Transparent is black with opacity 0. https://github.com/nacular/doodle/blob/999b98b48a4183f82d58e8cac57b93c9327515f3/Desktop/src/jvmMain/kotlin/io/nacular/doodle/drawing/impl/CanvasImpl.kt#L477
