In my attempts to squash the Security Detail View pull-down menu bug, I stumbled across some settings which appear to speed up QWin's display. When I open Q, the ever-present triple-paint seems faster. And I can actually drag a corner of the main window showing content and it keeps up pretty well, where before the lag was so great I set Windows to only show border dragging. All Q's unnecessary repaints seem a little quicker.
I guess I haven't poked around Win10 enough. I realize settings like this are hardware-dependent but wonder whether anyone else has made use of them. Or if any of you have made similar discoveries.
Here's what I found under display settings on my Asus laptop. Nothing was enabled on this page until I changed the settings.
(And no, I'm still unable to squash the Security Detail View pull-down menu bug without Q going all fuzzy on me.)
