I am creating an UI Design for a game but I keep running into the same problem. I do UI’s in Photoshop, I tried erasing every corner, but still the white lines appear like here:
How can I possibly fix this issue? What is the cause of it? Is it the Roblox Studio that does this? Please let me know.
I think this is the same problem I had before, I found out I could use this tool: https://js.do/rootmars/alpha_bleed_js
and run my images through it to remove some outlines. I do not know it it will work for you but its worth a try.
