Do you have available to share the log from the journal at the time when
the freeze happens?

Does this happen with any game, or just the one you cited? There are many,
many ways to do full screen on Linux.

Also, does it happens with primus as the bridge? apt-get install primus and
optirun -b primus ...

I won't have access to my optimus laptop for a couple of weeks to try and
reproduce, but I often run steam games full screen and I've never come
across this issue before.

Kind regards,
