Did you install other software that might be looking at the project “behind the scenes?” Keyboard extenders are notorious for this, but they aren’t the only potential culprit.
Did you add a lot of material, particularly research material, to the project?
Did you change your work habits? For instance, did you go from writing individual scenes to editing the entire manuscript in a large Scrivenings session?
If you step away from the computer for five or ten minutes with Scrivener open, is scrolling still jerky when you come back?
as mentioned before i still suspect remnants of Grammerly (or other software or even anti virus software) interfering. if it was Scrivener other people would have noticed.
Uninstallers are often not perfect. Fact is you have a unique problem. Perhaps use apple care and get apple’s help or if an apple store nearby get a genius appointment.
also, when you see the jerky response pull up the process viewer, or run “top” in a terminal window. what other processes running that may be interfering or consuming CPU. perhaps the font server “fontd” or other?
Neither do I frankly, but %CPU means percent of CPU being used. If you kill Twitter (which is consuming more than half the CPU) is it better? I don’t see Scrivener in you screen shot. CPU consumption as you report sounds high. Perhaps something corrupted. Have you removed and reinstalled it yet?
Me too. I’m out of ideas. Clearly something is interferring with it. Some other process (fontd, anti-virus, … something). Dunno, other than I don’t think it’s singly down to Scrivener.
Well, I’ve narrowed it down. I write solely in Page View, and didn’t give it any further thought. Turns out that hiding Page View or going into Composition Mode solves the issue.
It’s still annoying though as I much prefer the visual structure of Page View.
Page View is more demanding for the system because Scrivener has to reflow the text to place page breaks as you write. That’s especially true if it’s a large Scrivenings session (more text to manipulate) or if there are complex formatting elements like images and tables.
