For reference, the flicker does not occur with 4.2.8-300.
Also with 4.2.8-300, the external mini-DisplayPort does not work.

Skylake support didn't really land until 4.3, but it isn't complete in 4.3 either.  4.4 is likely a better option but it will be a few weeks before that hits Fedora 23.

*********** MASS BUG UPDATE **************
 
We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 23 kernel bugs.
 
Fedora 23 has now been rebased to 4.7.4-100.fc23.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.
 
If you have moved on to Fedora 24 or 25, and are still experiencing this issue, please change the version to Fedora 24 or 25.
 
If you experience different issues, please open a new bug report for those.
