Severe input lag when typing in chat, with latency increasing as performance decreases. Game controls are unaffected, but "bleed" into the chat if it's opened right after moving, resulting in a "ddddddwwww " style burst in chat. The key used to open chat is also often typed into chat.
The input lag becomes more apparent as game FPS drops / destabilizes.
The issue was never encoutered on any previous versions

Still an issue, even after changing desktop environment.
The issue appears during performance (FPS) drops, and gets worse the lower and less stable the FPS is. It also occurs for every linux user I know.
Can confirm I have major input lag with issue going worse with lower fps
My java version:
openjdk 10.0.1 2018-04-17
OpenJDK Runtime Environment (build 10.0.1+10-Ubuntu-3ubuntu1)
OpenJDK 64-Bit Server VM (build 10.0.1+10-Ubuntu-3ubuntu1, mixed mode)
I have linux too, I'm running linux mint with MATE and I don't have this issue.
This is probably related to the Garbage Collector.
Try these options:
-server -XX:+AggressiveOpts -XX:+UseConcMarkSweepGC -XX:MaxGCPauseMillis=10 -XX:ConcGCThreads=16 -XX:-CMSClassUnloadingEnabled -XX:+AggressiveOpts -XX:ThreadStackSize=2048k -XX:ObjectAlignmentInBytes=64
Also your Java version might help.
