Windows 10 Lag/No Refresh
Screen doesn't fully refresh upon opening or making any changes, leaving large parts of the screen blank and having to "wave" the cursor over them to get them to reappear. Also, any changes made to an individual item -- i.e. credit card, passport, entry -- takes several seconds to refresh/redraw, thereby slowing all interaction down to a lag. Using Windows 10, version 1809, build 17763.379.
