Decals overlapping on transparent parts

A few weeks ago I started a new project San Francisco International airport. I put decals on the windows for a darker look on the outside but a more clear view on the inside. I placed some tree models inside made of decals but the decals appear to be overlapping each other when looking at them from certain angles even though they’re not inside each other. Are there any solutions to fix this? Examples in images posted.

Have you tried using surface guis and see if it still happens? There isn’t really a workaround if you want to use decals, they overlap globally
