Minecraft 1.7.10 (also tested on 1.0 release) leaks memory in form of 1Mb
memory regions mapped to `/dev/dri/renderD128` (observed in /proc/[id]/maps)(it
seems new ones appear and old ones stay until program termination; probably it
has something to do with chunk loading/unloading since it seems new ones don't
appear when you stay still). Tested on java 8, happens with both openjdk (from
ubuntu 18.04 repositories) and oracle java (taken from here
https://www.java.com/en/download/ ). Leak also happens with
LIBGL_ALWAYS_SOFTWARE=1 set.
Might be worth noting that I use additional kernel boot parameters (iommu=soft
idle=nomwait rcu_nocbs=0-7 acpi_enforce_resources=lax) (some or all of those
are said to lessen system freezes (known problem with Ryzen 2500u)).
