Dear Mojang studios,
I would like to make you aware of the problem regarding Open JDK Platform binary. When Minecraft did not require Open JDK Platform Binary. 
I used to be able to run 200FPS with 30 chunks of render distance. Now with Open JDK Platform Binary I am running 20 FPS with 2 chunks. 
This is basically making the game unplayable. 
It has nothing to do with the computer as it is quite powerful. 
I have looked it up and other people seem to be having the same problem regarding the issue with Open JDK Platform Binary.
This has been ongoing for quite some time and in my opinion needs to be fixed.
