I'm using openSUSE Tumbleweed (rolling release) and the kernel from Kernel:Stable (actually with two small AppArmor patches on top) so I already have kernel 4.6.0 instead of the 4.5.4 kernel in Tumbleweed.
uname -r: 4.6.0-4.gaf7ce24-default
uname -m: x86_64
I'm using a laptop (Tuxedo Book BC1703 with i7-4710MQ CPU) with intel graphics and two screens (laptop display + external screen via HDMI), but also see this bug when the external screen is disconnected.
Kernel 4.6.0 causes the laptop screen to blink / flicker as soon as X starts (both login manager and in KDE) which makes the laptop display unusable and hurts in the eyes. This blinking is also reproducable with "X -retro".
I can "fix" this by booting 4.5.4, so this is clearly a regression in 4.6.0.
Also, booting kernel 4.6.0 with i915.enable_psr=0 stops the blinking.
Reproducable: always (the blinking with 4.6.0 without boot parameters, and also the non-blinking with i915.enable_psr=0 or kernel 4.5.4)
I initially reported this bug on
You can find logs (dmesg with drm.debug=0x0e), hardware details and some other details there.
If you need more information, just ask ;-)

Can you try 4.7-rc1?
4.7 rc1 sounds old ;-) I tried with kernel-default-4.7.rc3-1.1.g59af2d0.x86_64 from the openSUSE Kernel:HEAD repo.
Unfortunately the laptop still blinks with 4.7 rc3 :-(
