The EA 8 build of Project Lanai [1] was posted today at 

EA 8 Build 17-lanai+1-2 (2020/12/12)

Please do give it a try (-Dsun.java2d.metal=true) and let us know of 

One particular request :
To anyone who has a mac still running 10.12 - we don't expect Metal to 
run (it requires at least 10.13
and maybe even later by the time it is final) but we would like 
confirmation that nothing in Metal
prevents OpenGL running on older releases.
Note there is currently a hotspot build bug unrelated to Lanai that 
prevents running on 10.10
and maybe 10.11 but 10.12 will be a useful data point.

EA 8 contains the following new bug fixes relative to EA 7
