Those lines doesn’t show up on photoshop, only when i upload the image to roblox
I’ve done this before with other images but i think of it as bad practice and want to stop doing it (also this would involve turning every layer white and changing their colors in robox)
This is the current method i am doing right now with the external source from the other post that i linked here: UI White Lines Bug. But as mentioned on the post, if possible i would like to solve this problem without having to rely on external sites and etc
