Education Wanted: Windows 10 64 now Stable, Why?

Follow my Win 8 tweaks in the manual or helpfile... Win 10 is very similar.

If there is such a thing as 'show window contents while dragging', you can try disabling that one.

That option was one of the Windows Tweak options I went back & I deliberately enabled for another program. Unchecking that option in "Adjust the appearance and performance of Windows" settings fixed that resizing causes slipped buffers issue completely. (For others, you can search by Start in Windows 10 for "performance" and it comes up first in my Windows 10 - internet searching is disabled on my system.) It makes perfect sense that this applied directly to the re-sizing window issue. I totally forgot I re-enabled it at some point.)

Thanks again guys, you were right on!
