Yes I am embedding fonts.
Canterbury.ttf for dropcase.
Georgia.ttf for all other text.

I have opened widget at the bottom of the preview page, and gone thru the seven items there but don't see any issues?
Can you be more specific as to where to look?

According to a Google researcher, there are slowdowns and memory leaks associated with a Windows 10 security feature called Control Flow Guard that actually never frees memory in processes that open a large number of threads with different starting locations (such as the chrome browser or Sigil).
This can be especially troublesome on machines with lower amounts of memory as the only way to get the memory and speed back is to restart Windows. Restarting the impacted program will not help.
The slowdown part has been fixed in a recent Windows build. According to Google researchers Microsoft still hasn't fixed the lack of memory being freed even when an app exits (ie worse than a leak which is freed when a program exits).
The newer Qt webkits use multiple threads to walk the javascript stack to garbage collect, multiple threads to load resources (images, fonts, etc) and even multiple threads to run the gui. On my Mac, I once counted 43 different threads active when launching Sigil with a large book. Part of the reason for the large number of threads is that my cpu has 4 actual cores and therefore 8 logical hypercores.

Windows 10, version 1803, I'm not sure what update number it is but I have only had two failed updates.
