Over at Hackernews is a link to a discussion on how the Intel Management Engine (ME) is preventing screenshots, by bypassing the host CPU.
If you're on an Intel machine that you've purchased in the past 2-3 years, that computer almost certainly has an Intel Management Engine. You might not know what that is, and that's okay. You may also be unaware that the operating system on your computer could be leveraging features in the Intel Management Engine when consuming DRM Media.
This links to a blog posting on the Intel ME in response to Rosyna Keller's twitter posting about being unable to take screenshots from Netflix (The Rosyna of the article title).
The core of the technical detail is taken from Igor Skochinsky's presentation on the ME (PDF Link) . The article raises the questions over the position of the ME in the system and the security implications of the ME subverting the host machine hardware outside of the main processor:
Given that the ME sits in a position where it can configure the chipset and operate on the PCI bus, there are some serious security implications here I wish I could mitigate. Among them is the ability of the ME to run arbitrary code on the host CPU via option ROMs or presenting a disk-drive to boot from. Also among those abilities is the possibility to perform DMA to access host CPU memory. And another one is the ability to configure and use PCI devices present in the system (such as the ethernet card).

...but the annoyance is real
using Ctrl-C/Ctrl-V to cut/paste screen shots of 'stuff' has been a lifesaver MANY, MANY times in my work...
not to mention, WHY do mappers NOT want you to use their maps any more ? ? ? (meaning: WHY do mappers want me to USE THEIR method of using maps instead of what works for me?) in my line of work, need little map snippets ALL THE TIME; i don't even care if it has their watermark, name emblazoned, whatever... i just want an IMMEDIATE method of cutting/pasting the map snippets i need, and Ctrl-C/Ctrl-V worked fine until they decided to get all snippy about it... i don't want to use your stupid site, your stupid tools, your stupid ads, etc, etc, etc; just let me cut/paste your stupid map WITH your stupid name on it, and i'll be happy...
