Simultaneously pressing space or w,a,s,d results in inconsistent movement when compared to 1.12.2.
To repoduce: Be Using Linux I have confirmed this with other Linux users. This bug is not reproducible on Windows or Mac OS. It is not a hardware issue as behavior changed between the very first 1.13 snapshot and 1.12.2, and returning to the older version has reliable movement.
Press space and w simultaneously. You will either fail to jump or fail to walk forwards. This makes movement unreliable and aggravating at times, as even holding down a key sometimes won't register.

It's a GLFW issue. You can contribute here if you want to https://github.com/glfw/glfw/issues/1112
For me, pressing w+space usually works, only sometimes there's a delay between jumping and walking forwards. Pressing and holding w+space+ctrl or w+space+shift simultaneously will always make me jump in place. That started with the early 1.13 snapshots on Arch Linux.
