Sometimes, depending on what I'm doing, if I have multiple windows open and one is overlapping another, the one in front will seem to "disappear", but in reality the contents of the window behind it is being "drawn" over the window in front. When the window in front is moved, the "drawn-on" parts stay with it until one of two things happen. The window will be redrawn properly if I drag it off the screen and back, or if something on the window itself changes (such as highlighting a selection or hovering over a button that has a mouse-over effect). Only the parts that change or are dragged completely off the screen are restored to normal.
I notice this most when I'm working in specific applications. In Adobe After Effects, if AE is in the back and I've got something in front of it (even one of its own dialog boxes), this can happen. In Valve's Hammer World Editor software this happens. It can also happen with Media Player Classic if I have a video playing and have another window in front of it.
This problem seems to happen at random.
I updated to the latest video drivers, but the problem persists.
Based on what I know so far, I'm wondering if it's some kind of codec or video rendering issue. Before I go messing with my codecs, I'll wait to see if I get any responses here with other ideas. This problem is extremely annoying because while I'm working on projects I'm constantly having to drag my windows off screen and back just to get them to normal.
Thanks in advance for any help.
I uploaded a video that actually shows this happening. It's here:
It starts happening just after the 2:20 mark. The video is available in 1080p so you can see everything clearly if you go full screen with it.
