Description
Steps to reproduce
Reproducible with flutter 3.27.1, introduced in commit fc01196
Not reproducible with parent commit e466195 and not reproducible on 3.24.5
- Run the sample app on an iOS physical device using Flutter version 3.27.1
- Pan down on the main page
- Tap on the next arrow to go to the next page in the sample app
- Move the app to the background by putting another app in the foreground
- Move the sample app back to the foreground
- Observe console errors

attempting to reproduce with a binary search on various flutter commits, the first commit introducing the issue is commit fc01196
note that today's master branch commit 2d17299 does not exhibit the issue
Expected results
Expected no exceptions
Actual results
After putting app in foreground after putting it in background, images in the UI fail to render with the following error to console:
Exception: Image upload failed due to loss of GPU access.
With an "All Exceptions" breakpoint I get the following stack trace:
MultiFrameImageStreamCompleter._decodeNextFrameAndSchedule (development/flutter/packages/flutter/lib/src/painting/image_stream.dart:1064)
<asynchronous gap> (Unknown Source:0)
