I suspected it was caused by a new graphics driver, and yep:

en.community.dell.com/.../20022225

According to this link, the new 22.20.16.4735 Intel HD graphics driver (from Dell) causes this issue. Version 21.20.16.4574 seems to be fine.

EDIT: I'm using 21.20.16.4727 from here: www.dell.com/.../driversdetails

Seems to be alright too.

I am using this third fix and seem to have no issues so far*
