Windows 7: not saving preview thumbnails

it shows wddm 1.1.

did you reproduce the results using the method i posted?

are you sure about sure about aero saving the thumbnails to video memory? It seems like thats where they would go after you minimize a window. If you ticked "save taskbar thumbnail previews" they should get saved to hard disk, otherwise the "save taskbar thumbnail previews" feature would be useless; as saving them to video memory is how aero works without ticking that option.

There is no information on what "save taskbar thumbnail previews" actually does. So saying it should be doing this or not cannot be said. However, there is nothing to do here. Turning off Aero empties the buffer which removes the previews. They are also removed periodically because resources are not infinite. Everything is working as designed.

EDIT: The setting in question changes this Registry value: "AlwaysHibernateThumbnails"

okay ill agree to disagree. I just cant believe that aero peek is intended not to show a preview after playing a game. Imho, peek is not working as intended. Saying that it is, is nonsense. Its designed to let you peek into a window from the taskbar and its not allowing that to happen after playing a game. Its just unwanted side affect of how the "peek" code was written or a bug. As I stated many post ago, It would be quite simple to write code so that a call to peek into a minimized window without any current "peek" data would either:

A. wake up the app.
B. use a saved snapshot of the app.

OSX has been doing this for years with its expose app, its not new territory.

This is Windows not OS X. Windows does not update applications, applications update windows.
You have two choices, you either keep DWM active with a full buffer and steal resources from your game. Or you turn off DWM clearing its buffer giving the game all resources. So which do you want?

And what you think is simple is not simple. Because it is not possible to do that. To "wake up" a minimized application is not part of the communication chain. A application decides when it issues a new "paint" to the underpinnings.

solid information here my good friend. Im am curious to how the software engineers behind osx can pull off this feat if its impossible to do. my experience with coding is anything is possible. for example you could write code that makes the application think that its been restored so it 'issues a new "paint" to the underpinnings'. the impossible becomes possible if you think outside the box.

so how do i set DWM to stay active? Id like to use this feature for any of my games older than 2 years old.

Ill also be honest with you as a fellow programmer just because something happens does NOT mean its intended. If i write a application to talk to other people over aol instant messenger and it saves resources by not telling you that you have incoming messages while my app is minimized that is not a feature. I'm trying to save resources and accidentally made the the app not function as intended. ITS a bug. Overall im saving cycles but in the big scheme of thing my app is broken.

OS X uses a different windowing model then what is used in Windows. It is up to the application whether it repaints itself while minimized.

Anyone ever get empty preview thumbnails?
On taskbar preview thumbnails, usually you get to see the content inside the window. Sometimes, however, and I'm unsure of the situation that causes it, the thumbnail will not be there, but you end up with just a blank box with the program's icon inside. The way to fix this is to make active that...
