Performance of control rendering can be poor when running in debug state #1174
Description
I spent a goodly amount of time over optimising page performance and messing with graphical settings and css trying to improve a very perceptible 'lag' in the webview2 resizing and dragging - e.g. css positions content bottom right would 'drift around catching up to the window border' when resizing and moving the main WPF window, and in general the window performance was not 'smooth'.
I was nearly about to declare it 'crap' when I tried publishing the app and running it without debug. The rendering performance improved dramatically, and whilst not eliminating the drift/delays/lags/black un rendered areas completely - it improved to something I can now live with.
Forgive me if everyone knows to do this sort of confirmation testing of a performance issue - I'm still learning :-)
Mentioned in case other people have also experienced the poorer performance and don't realise it's a temporary thing.
