Font on Ubuntu becomes funky with the JRE bundled with 2017 EAP (can be fixed with JRE from IDEA 2016)

I installed EAP because I need Vue.js support. However, the font became visibly funky, as can be seen on the left, as compared with the normal IntelliJ IDEA Ultimate 2016.3 on the right.

I copied the bundled jre from 2016.3 to EAP and the problem was solved. Curiously, both `release` files in the jre folders show exactly:

JAVA_VERSION="1.8.0_112"
OS_NAME="Linux"
OS_VERSION="2.6"
OS_ARCH="amd64"
SOURCE=""

so I really don't know what the difference is.

Hopefully this issue will not carry over to the actual releases of IntelliJ 2017 products. If a problem was already fixed in 2016, it shouldn't regress.
