--- Comment #5 from Olivier Berthier <olivierx.berthier at intel.com> ---
Yes, I confirm, without additional screen there are no crashes and I only have
one fail with fbc-farfromfence:

IGT-Version: 1.12-gbfea74a (x86_64) (Linux: 4.3.0-rc7-nightly+ x86_64)
Primary screen: eDP 3200x1800
FBC last action not supported
FBC status:
FBC disabled: mode too large for compression
Compressing: yes

Test assertion failure function farfromfence_subtest, file
kms_frontbuffer_tracking.c:2798:
Failed assertion: false
FBC disabled
