Windows 7: not saving preview thumbnails

two questions.

1. Is there anyway to make the previews/aero peek work as intended?



This happens to me daily and is very annoying, it makes all the preview functions of aero useless. This usually happens after playing a full screen game or after computer goes to sleep etc.. I have already ticked "save taskbar thumbnail previews"

2. I doubt this is possible, but is there anyway to make the previews live when app is minimized?

Welcome

Right click on task bar and choose how you want windows shown. Ihave nothing checked and it works as expected.

I appreciate the reply, but i have no idea what you are talking about... right click on task bar nets this menu:
As you can see I have nothing checked on this menu besides "lock taskbar"



Also here is another example of the problem.

It is working as attended. It just happens it cannot hold onto the required information during gaming or sleeping. I am assuming you are using WDDM 1.1 drivers.

Application level control. Freezing the previews for minimized applications saves resources.

Thanks for the reply.

Is wddm the graphics driver? if so im using the newest nvidia driver. Maybe it has that driver cooked into it? other than that i dont know how to check what im using.

I really have a hard timing believing this is how the app is intended to work. because it makes aero peek useless under these circumstances. I feel like its just a nasty side effect of how the previews were coded. Its def possible to write code so that minimized apps aren't actively processed, but during a call to preview it will wake up the app.

I was hoping there was a registry to key to do this, or at the very least it could save a snapshot preview that it could go back to if no current data was available.

you can see here, that the latter feature was intended to work.



If either of my hopes can be accomplished someone please let me know how.

However if my problem is caused by outdated wddm drivers then someone please tell me how to update... thnx in advance to an awesome Windows 7 forum.

bump for justice

last attempt for an answer

Did you not get your answer a few days ago? Anyways, let's try to diagnose your problem, shall we?

Which version of Windows 7 are you using?

You mentioned this happens after playing afull screen game. Which game?

What graphics card do you have?
Is it certified as Aero compatible?
How much memory does it have?

How much system memory does your computer have?

thanks for the reply, i appreciate it.

i get the same problem in both my Windows 7 machines

my specs are: desktop | laptop
OS & RAM: Windows 7 unltimate x64 4GB ram | Windows 7 professional x64 4GB
GPU: 8800gt 512mb | i3 , both with latest official drivers.

game shouldn't matter, but its happened with every game Ive played... ut2004, quake3, bioshock, bioshock2, crysis... the list goes on.

this system is much more than needed to run aero correctly imo.

The problem happens when you play any game full screen because aero gets temporarily turned off. You can duplicate this easily by opening a couple of windows. then keep some of them opened and minimize some of them. Now turn aero off and then back on again. all the minimized windows will not have a preview now. because they aren't being actively drawn.

this is exactly what happens when you play a fullscreen game. however im not exactly sure what causes this problem during a deep sleep. I'm sure it is similar.

Windows should be "saving screen shots" (if you have that box ticked that i posted earlier) that will be used in a situation like this, but it doesn't.

Open DXDIAG (Start [WinKey] > type "dxdiag" enter) Go to the Display tab, right side box "Drivers" which "Driver Model" is listed? WDDM 1.0 or WDDM 1.1? To me it appears your problem is nothing more then video memory being cleared for your games and during sleep. Using WDDM 1.1 drivers video memory is exclusively used versus WDDM 1.0 where a synced duplicate is kept in system memory.

But no, there is no setting.
