Entire Linux computer crashes once menu screen is loaded, since LWJGL 3 used

When launching Minecraft in affected versions, the game launches correctly, running correctly (Mojang logo) until the menu screen loads. Once the menu loads, the game runs as expected for roughly two seconds, then the entire computer hangs, not responding to mouse or keyboard input, the game frozen.

There is never a crash report; no useful or out-of-the-ordinary information ends up in the log file (except, perhaps, "LWJGL Version: 3.1.2 build 29", which is, of course, new): https://gist.github.com/towerofnix/a0f455ecd9e03f992984c87b0984fb51

No previous version of Minecraft had this issue; I can still run those versions as I've always been able to.
