Minecraft Xbox One Frame Rate drop?

Problems with Minecraft Xbox One (original)?
Hey guys!

I'm building a recreation of the Disneyland Resort on my Minecraft Xbox One edition. It's the original version, not the bedrock/better together one. I have noticed that in a particular area, the frame rate kind of drops a bit for no apparent reason, and that on colored signs, the letters/words would loose their color and turn black. It's really hard to explain and it only happens in this particular area of the map. The frame rate stutters a bit there and it's really annoying. I have a friend who is recreating the Disney parks in Paris at the same scale and detail, and his world is just fine. Note that I have the digital version of the game while he has the disk version of the game. Could that be a factor? Does the disk version run better than the digital?

The disc version and the download version are identical.
