Question about rounded corner columns

[kevincianfarini]

I'm using Vico to render a bar chart with rounded corner bars. I've noticed there's some fragmenting where the rounded corners are drawn. The below screenshots illustrates this for bars of varying widths.

Is there anything I should be doing to ensure the smoothest possible corners on these bars? Here are the shapes I'm currently using to draw my lines.

val positiveRoundedCornerShape = Shapes.roundedCornerShape(topLeft = 3.dp, topRight = 3.dp)
val negativeRoundedCornerShape = Shapes.roundedCornerShape(bottomLeft = 3.dp, bottomRight = 3.dp)
val line = LineComponent(
    shape = if (value.toDouble() < 0.0) negativeRoundedCornerShape else positiveRoundedCornerShape
)

Hello, please provide a MRE. It doesn't happen in the sample app with the same Shape.

I took my screenshot on an emulator as well, but I've never seen this issue before neither on real devices, nor emulators. My first guess is that your GPU does not play well enough with your emulator.

Can you see if you have similar issues in other apps? Can you also check whether you have the same problem on a real device?

[kevincianfarini]

Sure. I'm also going to try on an API 34 emulator.

There's no artifacting on an API 34 emulator.

Looks like this is perhaps an anomaly of the Pixel 3a API 29 emulator. My real device, a Pizel 3a XL API 29, shows no signs of artifacting either.
