We have an issue where images in our UWP app are sometimes getting loaded with the wrong image and sizing. The first time the images seem to load correctly, but then sometimes the images will be wrong after leaving a page and coming back. This seems to happen all over the app and happens with multiple kinds of image load code. Examples of problem: ![42334-incorrect-pre-check-1.png][1] ![42335-incorrect-pre-check-2.jpg][2] ![42235-incorrect-workspace.png][3] Correct Workspace: ![42342-correct-workspace.png][4] Code Examples Where It Has Broken: ![42361-code-example-1.png][5] ![42236-code-example-2.png][6] [1]: /api/attachments/42334-incorrect-pre-check-1.png?platform=QnA [2]: /api/attachments/42335-incorrect-pre-check-2.jpg?platform=QnA [3]: /api/attachments/42235-incorrect-workspace.png?platform=QnA [4]: /api/attachments/42342-correct-workspace.png?platform=QnA [5]: /api/attachments/42361-code-example-1.png?platform=QnA [6]: /api/attachments/42236-code-example-2.png?platform=QnA

2020-11-30T16:35:16.637+00:00 Like I said, it is very sporadic. I was hoping that someone with a deeper understanding of the UWP framework than me would have an idea of what could be going wrong (like using regulatr binding in ItemsControls or something).
I'll see if I can reproduce it in a sample project, but so far it seems to be random.
Here is another example of someone who saw it in the past, but didn't seem to get a resolution: https://forums.xamarin.com/discussion/153224/uwp-occasionally-an-image-will-display-the-wrong-source-using-the-bounds-of-the-correct-source

2020-12-01T09:25:04.493+00:00 @Kyle Rudd We could not reproduce your issue. And if there are many images in your page, you could try to cache the page by using Page.NavigationCacheMode. Set the value of
NavigationCacheModetoRequired. -

2020-12-02T09:59:08.327+00:00 @Kyle Rudd It will be better if you could provide us with a sample because we can not locate the problem without reproducing the issue.

2020-12-02T16:09:17.72+00:00 Sounds good. I'm working to produce a sample, but I haven't been able to repro in a simpler project yet.
Are you ok to wait while I attempt to make a sample, or would it be better to close this ticket, then reopen a new on when I have a sample?

Tom Hollander 5 Reputation points2023-12-21T23:47:04.9066667+00:00 This is still a real issue in 2023. Same symptoms as listed above - issue only seems to affect production builds after the app has been running a while. No reliable way of reproing but it definitely happens.
