I’m trying to use a 9-patch panel sprite, but with repetition these weird grid lines are showing for some reason:

?

Context:

• Camera is at 2.0 zoom level
• Camera centered on top left screen quadrant (flooring doesn’t work)
• Project is pixel-perfect
• All margins set to 16px
• Base size set to 64px
• Image size is 64px
• Inner solid area starts at 16th pixel

Could someone more experienced please help me out a bit? What am I doing wrong here?

Thanks in advance!

For now I have decided to use stretching instead. This results in losing the edge patterns, but they’re still there on the corners. You have to cut corners for efficiency when you have a deadline. Things can be polished off after the jam has concluded.
