Dark edges on rectangle image

Hey guys I was experimenting with creating retangles with rounded corners. When I uploaded them to Roblox as a decal and inserted it into Studio, I noticed a dark outline on the curves. What can I do to get rid of it?

Sorry, it may not show well on the image I provided.

Can you please provide a couple more photos which include more of the surroundings.

Sure give me a minute to capture them.

So if you look to the corners where it is rounded, thats where the problem is.

Wow yeah I’ve had this problem many times, this is the reason I dont use the ROBLOX preset UI’s. It killsme how they’re a little fuzzy and darker. I think it could just be a rendering bug on behalf of the engine as if you look closer they’re not actually rounded it’s just pixel size sloped like stairs.

What do you mean by preset UIs? That was an image that I created then uploaded.

When you make text buttons and labels the presets are “RobloxRound” etc. So now if you’re saying it’s an image you inserted then I believe it’s a studio bug when rendering curves.

This happens because of “Bilinear Interpolation”.

Thanks! I’ll have look at it to see if I can fix it.
