Win 10 visual issues (windows render slowly, selection box sluggish)
I've got a fairly recent build (specs are below), and the OS performance has been absolutely sluggish and glitchy ever since upgrading from Windows 8 to 10. >:-( Video performance in particular. I get this intermittent and long lasting issue where system and application menus (but strangely no problems in a browser) won't render properly and/or render REALLY slowly. They're either just the frame (desktop showing through), lacking the text options, or the drop-downs wont show the text. Selecting with the drag/box tool is an absolute nightmare too, either not displaying (or highlighting selections that are in fact selected, and/or won't go away after dragged), or reacting with an enormous delay. We're talking 500 ms to a second or more here! The system is effectively unusable when it's doing this.
Weird part is that it'll respond that way for an hour or two on end, then all the sudden start behaving normally. The system itself is a beast (I do CAD design and music production), PLENTY of horsepower, workstation video card, liquid cooled. I've tried updating all the drivers, rolling back video drivers in particular. I tried upping the paging file as well. No bueno. Is there a solution here that I'm missing? Can I roll it back to Windows 8?
