Major bug with iCloud restore and the multitasking menu that compromises privacy.

Question

Hello there,
I very rarely post on these forums but I’ve discovered what I think is a pretty serious bug. I’ve already sent this as feedback to apple but id be interested to know if anybody else is able to re-create it or has already stumbled across the problem.
I have been able to recreate this problem twice by creating an icloud backup on an iPhone 6 (iOS 8.0) and restoring to an iphone 6 (iOS 8.0).
The problem has to do with the multitasking snapshots that appear after double clicking the home button. On the iPhone it is my understanding that there can be up to 3 ‘different’ snapshots based on when the home button is double clicked and the orientation of an app:
a) The first is when you have an app open in portrait mode and then close it or click the home button to exit. Double clicking the home button from the home screen will then display the multitasking menu including a portrait snapshot of what was last seen in that app.
b) The next is when you're in an app that supports landscape mode and double click the home button whilst ‘in app.’ This displays a multitasking menu with landscape snapshots showing what was last seen when apps were open in landscape (note that if apps can only be shown in portrait than this is the image that will be shown and it will appear sideways).
c) Finally, there is the case when you have an app open in landscape and then directly close it or press the home button, and then double press the home button. This displays a multitasking menu with portrait snapshots; however, to my knowledge these snapshots never change (they will not show the last snapshot from when the app was last open in portrait mode).
The bug is that after restoring from iCloud, the snapshot as described in ‘C’ scenario gets set to whatever was in the icloud backup for scenario ‘A.’ Because this snapshot cannot be changed it is a major bug if for instance you have personal information in the snapshot. In my case, I have my bank statement permanently appear in the snapshot for scenario C.
What’s more, if I have safari is in landscape and then close it; then at some point I open the multitasking bar before opening safari again in portrait mode; then the snapshot flashes up in the actual app for around 1-2 second before disappearing.
At the moment the only solution I can see is to setup my iPhone as new but this will be a major hassle and lose all my settings etc.
Finally, it’s worth mentioning that I think this is a bug across all ios devices with multitasking; however, with the ipads there is an easy solution because you are able to orientate the home screen in multiple ways. This means its possible to update the snapshots in a way that you can’t do on the iPhone because the home screen is locked to portrait.

Answer 1

so to clarify, it appears that the multitasking snapshot for the following scenario will not update: open safari and turn to landscape, exit safari using home button or multitasking bar, then double press home button. That snapshot that appears for safari doesn't ever seem to refresh. Whatever is there is stuck there and whats more it will always pop up in the actual browser for 1-2 secs the next time safari is opened after completing those steps. Im not sure when the snapshot is initially created - it must be the first ever time you close safari but as I said in my post, it also appears to be stored in iCloud backups. So I've tried:
a) hard resetting
b) clearing safari cache and history
c) resetting all settings
d) restoring from iCloud (as mentioned)
e) opening and closing closing safari using the multitasking menu (both the landscape multitasking menu that appears when you're actually in safari in landscape mode, and the multitasking menu that appear when you double press the home button on the home screen).
f) same as above except closing all tbs open in safari before then exiting.
