Well, that is strange. So I added the "--disable-gpu" suffix to the Evernote target line, and as I reported before, it worked fine after that. Until yesterday.
The suffix is still there, but the Evernote process is again too high. Not as high as before, but still too much for my liking. It now hovers between 5 and 7.5%. The fan of my laptop is again running higher than it should be.
This really starts to annoy me a lot.
