--- Comment #3 from Andy Furniss <adf.lists at gmail.com> ---
I've of course tried various things sine reporting - Valley doesn't always
instantly lock. Unreal 4.5 Elemental got half way before locking.

Perhaps more interesting I managed to reset/fail resume just browsing - of
course I've done a lot of browsing without issue so far. The difference this
time was I had a huge ffmpeg/x265 encode going - it was using all my memory (8
Gig and swap had been used a bit), so it's possible memory pressure plays a
role - or maybe just a red herring :-)

I haven't managed to get a reset running timedemos on openarena or xonotic so
far - will try with memory pressure as time allows.

The reset when browsing -
