Does this i915.enable_psr=0 solved your issue?

Panel Self Refresh (PSR) is a feature that increase the power savings my
letting a static image on your screen and shut off some display components
allowing you save more power. when the screen needs update everything is on
again hw exit psr and you get screen updates. 
At some point on 3.16 or 3.17 we tried to enabled it by default but it caused
some frozen and blank screens and it was reverted. I'm afraid that you are
using a kernel with this feature enabled since the behaviour you describe is
missing screen updates when not moving the mouse and not getting any gpu error
state.
So please let me know what is the output of your
/sys/kernel/debug/dri/0/i915_edp_psr_status

Thanks,
Rodrigo.
