Adobe AcroCEF using too much CPU

Question

I've noticed recently that simply opening a PDF file and leaving it open for a minute or two makes my CPU fan kick in. The culprit is AcroCEF.exe. It consistently is using quite a bit of CPU power. It is not spawning several copies of its process, like some others have noted, but just the one running is enough to make me not want to open PDFs using Acrobat. What is this thing? Is there a way to fix it?

By the way, I'm running Windows 10, latest updates, and Acrobat DC, latest version.

Same issue. This started recently. It's a single "Adobe AcroCEF" process that's hogging so much of the CPU the fan goes into full gear the second I launch Acrobat.

Edit: Updating Acrobat seems to have fixed the issue, but I should mention that I had to do the update from within Acrobat, via Help > Check for Updates. For some reason the Creative Cloud Application itself didn't detect this update and do it automatically.
