Xcom 2 WoTC crash when run from LSI snap

[ninjaguardsheep]

Xcom 2 War of the Chosen crashes after a short period of time when run from the LSI snap.

The game launches and runs OK but will crash after a short period of time (less than 5 mins), the crash can occur anywhere within the game; in mission, in menus, in character creator, etc.

The game doesn't appear to know it has crashed, no errors are printed to the command line and no dump files are generated.

log_native_runtime_enabled.txt
log_native_runtime_disabled.txt

The crash occurs with the native runtime both enabled and disabled, I have attached the logs for both runs.

I am using an AMD R9 270 GPU with the open source drivers.

Any hints on how to debug further would be appreciated.
