Rendering error in the manual in the openos part, going down a little (I don't know if it is from optifine or opencomputers)

[ELJOKER900]

What happens is that when in the openos tutorial part of the manual when you lower down a little the top and bottom of the Minecraft game turns blue, as if it were a chunk downloading and when I close the manual everything goes back to normal, In the optifine I have the quick graphics set as additional data

I'd suspect Optifine shenanigans here. Test without it.

happened to me I think it might be ALSO your graphics card because I don't have any problem with my GTX 1650 super but I have that issue with my geforce 210
