I know that Faithlife/Logos made the decision several years ago to move to a new Windows-based platform (WPF) that is graphically intensive and really slow on many systems with slower processors and hard disks.
I wonder if they can move to a lighter platform that runs faster on a wider range of machines like many of their competitors?
Qt would be a good choice as it is cross-platform and very fast. https://en.wikipedia.org/wiki/Qt_(software) Scrivener is Qt based and runs fast on all of my systems.
