After putting the laptop into sleep to disk and resuming got some corruption of the display. In updated areas of windows. Mainly the top window bar, popup menus, and changed text. After 10 minutes it disappeared on its own and is now working correctly. Looking in the logs I see these two messages. The first one was during the resume of the kernel and the second was when the corruption stopped.

[drm:i915_get_vblank_counter] *ERROR* trying to get vblank count for disabled pipe 0

[drm:drm_wait_vblank] *ERROR* failed to acquire vblank counter, -22

While trying to reproduce this bug and get intel_reg_dump output the first message appeared again but the corruption did not. nor did the second message happen.
