When pressing ctrl (or other bound sprint key) at exactly the same time as W (or other bound walk key) the player stays stationary. This issue occurs in 1.13.x and 1.14 but not previous versions.
Environment
Linux mint 19.1 cinnamon, latest launcher that will install (launcher updater is also broken and I will pop a report for that too), issue occurs with both openJRE and Oracle Java.
