Corruption with xf86-video-intel 1:2.99.917+604+gff0ab2c-1

The latest version of the Intel graphics driver seems to cause strange corruption on my Skylake Thinkpad.
Downgrading to +587 release in testing causes this issue to disappear. Any idea what's going wrong ?
(I use the following parameters "intel_pstate=no_hwp intel_idle.max_cstate=0 i915.preliminary_hw_support=1", with Linux 4.5.0-1 .)

I'm seeing the same corruption on a Skylake NUC -  already using enable_rc6=0 for stability.

BTW skylake is no longer preliminary_hw since kernel 4.3 so that param isn't neccesary.

Looks like it's fixed in +622 released.
(Thanks for the heads up on the kernel args.)
