I recently opened my world with falling block entities in 1.13 prerelease and they all converted to the same block. This may be that 1.13 redid the blocks and since it is a falling block, it converts to default. 

I'm sorry, I realized this was only a problem for optifine because when I switched back to normal minecraft, it did not do this. I'm sorry for the inconvenience.

This has become a little different. This only happens when I'm not in fullscreen and in windowed mode. 1.9 made better fullscreen performance than that of snapshot 15w40b and greatly reduced the capability of running the game in windowed mode.

I cannot upgrade my driver software since it is incompatible with my laptop. 😞

THIS IS THE GAME OUTPUT!!!
