This^ would suggest it's a crash in the nvidia driver. Is this reliably reproducible? Or was that just one time crash? I'm not sure if there's much we can do about this.
Comment 2 Edward Nygma 2015-10-21 22:54:10 UTC 
Hi,

Just a one time crash, since I don`t remember seeing it occur since then. Hope it's useful in some way, otherwise you know better what to do with it :)
Comment 3 Martin Klapetek 2015-10-22 16:28:08 UTC 
Thanks, it's not really useful unfortunately, nothing we can do about this one as it's crashing in the binary nvidia driver and there are no 100% reproducible steps.

Sorry.
Comment 4 Thomas Lübking 2016-05-13 07:07:43 UTC 
Leaving aside the concurrent ::renderBatches call, this is similar to bug #355026 which was duped to bug #355578 where the crash happens in MESA *without* the concurrent calls.
Smeels more like a bug in QtQuick than in MESA & nvidia at the same time.
