high cpu usage indesign
I am periodically experiencing high CPU usage with InDesign 13.0 x64 on Windows 10. The CPU remains high even while not actively using InDesign and doesn't stop until I quit and relaunch the application. This issue only started happening within the past few weeks, probably after the most recent update.
I'm attaching a screenshot from the Task Manager showing 50% CPU consumption. Please note that my laptop is quad-core. That means InDesign is fully consuming 2 CPUs (4 threads) continuously.
Since the most recent updates InDesign will open multiple instances of Adobe CEP HTML Engine.exe while running consuming well over 57% of my CPU resources--over 22 instances the last time I opened it. This is ridiculous. No easy way to disable the plugins any more and none of the frequently referenced "solutions" work.

I see this too on Mac OSX (Catalina) on a 2014 MacBook Pro, and it is especially irritating because its very very good at wasting battery.
Basically over time, and on longer documents, I see ID start using more and more CPU, mostly in a "CEPHtmlEngine Helper" process. This can be true while using the app normally, or with only the Story Editor window visible, or even sometimes with the whole app hidden and theoretically idle.
Close the app and restart and all is well again, for a while.
I think there is a relation between this and the document length/complexity. For example, last time I experienced it I was editing a 70 page A4 document with about 60 images and over 10,000 words of text in a lot of different frames. Conversely, editing single-flow documents is less likely to provoke it.

InDesign 14.0.3 is using a lot of CPU and energy. No document is open, InDesign is running in the background but still uses over 50 % of the CPU and a lot of memory. Still this program is not production ready. I’m really disappointed about the quality of this release.
