Game crashing when loading a new world (via `tp` commands or using portals)

Not sure if anyone has seen this behaviour, but when running Iris and switching worlds, the game crashes. The normal crash report isn't generated, and instead it seems like the entire OpenJSK instance is failing. The error seems to reference an issue with the currently-installed NVIDIA driver, but the issue only occurs when Iris is used. Not sure what to think with this.
