Up until today's Xorg driver update the same behaviour occurred in F22 as well on this notebook. The issue is fixed by the latest Xorg Intel display driver version available in the stable repositories: 2.99.917.9.20150520.fc22 I can't test for F21 having clean installed F22 on the notebook but would say the same most likely applies.
