Exception: Image upload failed due to loss of GPU access on iOS Devices on 3.27.0-0.2.pre #159397
Description
Steps to reproduce
I don't have a reproducible sample yet.
This happens on a large-ish production app.
Expected results
No exceptions to be thrown
Actual results
Since upgrading to 3.27.0-0.2.pre, I see a lot of Exceptions in my Monitoring Service for iOS devices (iOS only, for now).
Unfortunately, I don't have a usable stack trace:
_Exception
Exception: Image upload failed due to loss of GPU access.

mechanism: FlutterError handled: false
additional context:
Either
flutter_error_details
context: thrown resolving an image frame
library: image resource service
or
flutter_error_details
context: thrown image failed to precache
library: image resource service
100% of these exceptions happen in .inactive lifecycle state:
flutter_context
current_lifecycle_state: inactive
default_route_name: /
has_render_view: true
initial_lifecycle_state: AppLifecycleState.inactive
I do not know if the user experience is impacted by this or what causes this exceptions to be thrown specifically.
Code sample
I can't produce a code sample at the moment.
I am open to spend more time on this if someone provides guidance on how to narrow the issue down if needed.

Hi @knaeckeKami, what version of flutter did you upgrade from? What version(s) of iOS are experiencing this issue?
Do you know what operation is being performed at the time of the issue? What device(s) have you seen this issue on so far?
knaeckeKami commentedon Nov 25, 2024
I upgraded from the latest stable, 3.24.5.
It seems to affect multiple iOS versions, I have these in my monitoring:
It does not seem to be device specific, I see these exceptions from iPhone 12 - iPhone 17.
I don't have good information on what caused this, but from the logs, it seems it might be related to precaching images.
I precache some images before some navigation events to avoid pop-ins.
danagbemava-nc commentedon Nov 26, 2024
Hi @knaeckeKami, are these network images or some heavy assets? Can you check to see if caching the images earlier resolves this issue or would the images be unavailable?
knaeckeKami commentedon Nov 26, 2024
I think it's related to loading network images, yes.
What do you mean by "caching the images earlier"?
I might be able to gather more information if someone has a clue from where an exception with the message "Image upload failed due to loss of GPU access." could come from, googling this message only leads to this GitHub issue unfortunately.
Searching in the engine code base, it seems that this line is hit:
https://github.com/flutter/engine/blob/acc32b477e944e44ea3b092209dccb0564a86fd2/lib/ui/painting/image_decoder_impeller.cc#L442

You mentioned you cache images before navigation,
I precache some images before some navigation events to avoid pop-ins., so I was wondering if you could do it earlier.Seem related to impeller, could you try with the skia renderer to see if you still experience this issue?
knaeckeKami commentedon Nov 27, 2024
The way I do it in these cases:
or
Other than precaching at app start (which would delay the start and could cause memory issues) I don't know how I could precache the images even earlier.
I can't release a Skia version to my users due to performance issues.
I did not manage to reproduce this issue locally yet.
Maybe someone with experience in Impeller can give some guidance on why this might happen, so I can find I way to reproduce it?

Thanks for the info.
Labeling this for further investigation and insight

This exception is thrown when many images are queued up for decoding while the engine does not have access to a GPU context. If the number of queued images exceeds some threshold, then older queued up images are evicted. From my perspective, this is working as expected?
This can only happen when the app runs in the background, at which point the images are not visible anyway. My recommendation would be to either ignore these errors or use the flutter lifecycle observer to avoid decoding in the background on iOS.
