The hardware acceleration was disabled, though I don't remember disabling it. Also the issue was happening with an active selection. Enabling hardware acceleration improved a lot, the CPU usage is now around 10% with an active selection. With no active selection there is almost no CPU usage as expected. I think I ran into this issue because I grab a lot of screenshots and when I paste them, they are selected by default. Just out of curiosity, why a selection cause such behavior? Thanks a lot for your quick and precise response.

Hi everyone, I've been experiencing a high CPU usage with paint.net when it's was supposed to be 'idle'. I'm running paint.net 4.0.12 with Windows [Version 10.0.14393], but this issue have been happening in the last versions as well. It's not just one thread causing the high CPU, but a few of them. I'm uploading an screenshot of Process Explorer to show more details. I don't when the high CPU starts, but it does not happen if I minimize paint.net, tough it happen if I just Alt+Tab to something else. If needed I can get more details (logs, dumps, etc) to get more information about this specific scenario. Congrats for this REALLY GREAT application. It's awesome. Regards, JRG
