Random system freezes - Intel HD Graphics 520
Getting annoying system freezes and wondering whether f.lux might be related, I've seen some past similar issues. Not sure what could be causing this, I've unsuccessfully tried to exclude possible causes. This is the driver Lenovo provides, I've tried removing it in the past and installing the latest directly from Intel with no change.
