memory leak visualvm shows rendering thread resets every 2000 megbytes(do not ban)

it is in a consent java gc causing it to lag here all the time 

i give it 8 gig to give it excess memory so it should be doing it at around 4 gig with the default jvm settings other then max memory

(been banned for reporting valid bugs by remaking  them when falsely closed made a alt got banned second alt just do your job and i am fine just invaild because we say so is not acceptable if you do say why thats all i ask)
