On 4.11 kernel I get very strange issues after start from cold boot.

When I log in and my graphic session is established after couple seconds my
screen freezes and starts whitening then returns to normal and repeats
freezes/whitening for few minutes. (I'm unable to record this behavior).

Meanwhile my screen starts HEAVY flickering (refresh rate is extremely low)
which stops after about 10-15 minutes. This flickering doesn't stop even when I
reboot my machine or reboot and start windows 10 session. (those issues don't'
happen in windows independently). After 10-15 minutes everything is back to
normal and I don't see anything suspicious.

I remember that I saw this weird thing in linux 4.7 (4.8 and 4.9 were ok,
didn't test 4.10). I tested boot with following options:

i915.enable_psr=1
i915.enable_psr=0
i915.enable_fbc=1
i915.enable_fbc=0

and they didn't help. I also tested this with linux 4.12.rc4.

It happens only if I start system from cold. Restarting it after the time
issues are gone doesn't trigger them again. Also it happens when I suspend my
machine and resume it long after. 

My system:

HP Spectre x360 Convertible 13
Desktop: KDE Plasma 5.10.1
Display Server: x11 (X.Org 1.19.3)
driver: modesetting
GLX Renderer: Mesa DRI Intel HD Graphics 5500 (Broadwell GT2)
GLX Version: 3.0 Mesa 17.1.2
