[Impeller] Impeller causes segfaults on older devices #175562
Description
Steps to reproduce
We enabled Impeller on our commercial app (Flutter 3.35.3) and users on these devices are now receiving segfaults caused by Impeller:
- SM-N975U1, Android 12
- SM-A805F, Android 11
- SM-G973U, Android 12
- SM-G973U, Android 11
- SM-N975U1, Android 12
- SM-N970U, Android 12
- SM-G973U1, Android 12
- MI 9, Android 10
Possible triggered by certain Lottie animations, but cannot be certain.

@stx Could be related to #171719 which has been fixed recently but isn't in latest stable yet but is available in latest master and beta. Can you check if you have similar code implementation in your app that might be causing the crash?
stx commentedon Sep 19, 2025
@darshankawar Thanks for sharing that issue. We don’t have that code implementation, but we do use Lottie, which performs extensive custom painting. I assume it does similar things to that code implementation, so it could be related. However, we don’t have the exact devices required to verify the fix.
I’m surprised that the fix you linked for a fatal crash regression doesn’t qualify for inclusion in the stable branch. Unfortunately, we lack the courage to update our commercial app to Flutter master, so we will continue to leave Impeller disabled indefinitely until stable catches up with the fixes.
Thank you for your help!
darshankawar commentedon Sep 19, 2025
Thanks for update @stx. The issue I linked may or may not be the same but I referred it to see if it relates to your case or not.
Can you provide us GPU / processor details of these devices ?
stx commentedon Sep 19, 2025
I'm not familiar, sorry. Just have these Sentry reports.
darshankawar commentedon Sep 19, 2025
I'll keep the issue open and label based on stacktrace, for team's attention.

@akshatAndMohit Thanks for the repro case. We are going to take a look into it. It looks like a problematic lottie file.
@stx seemed to report that the crash was "Possible triggered by certain Lottie animations, but cannot be certain." so we are currently assuming the two reporters are reporting the same issue.
@akshatAndMohit Can you also verify if the backtrace matches the original reporters issue? Thanks anyway for the helpful repro. case.
akshatAndMohit commentedon Oct 6, 2025
@chinmaygarde actually this Lottie working fine with Skia and with android Native but only causing problem with Impeller in Flutter
Youssef-Sholkamy commentedon Nov 27, 2025
Currently facing same issue on Samsung Galaxy S10 lite (SM-G770F) Android 13. After disabling Impeller and running the app on Skia, the issue went away. Some logs that might help with the debugging.

In version 3.35.6, my app also experienced a large number of crashes. The key information from Google Firebase Crashlytics is as follows:
1.According to the event reporting information, the crash occurs either during app startup or during usage.
2.RAM available capacity is very low
3.Most of them are Qualcomm GPUs:
F-52B: Adreno 619 GPU
OPPO OPG02_jp_kdi: Adreno 619 GPU
OPPO CPH2309: Adreno 619 GPU
OPPO A55s 5G: Adreno 619 GPU

Adding another data point for this issue class — same Adreno + Impeller/Vulkan
HardwareBufferallocation failure, but on a newer device (Adreno 720, Android 16) with a milder symptom: instead of a hard segfault, the engine recovers via a surface re-initialization, which shows up as a visible reload/flash on app launch before the app continues normally. Screen recording of the reload is attached below.Device
OpenGL ES 3.2 [email protected] (GIT@f8fe1c3431, I2d857631a6, 1764949614)(Date: 12/05/25)9161402dc0e134b3fb5adee5046b6e84b1a5e1c1Symptom
On launch, the app briefly flashes/reloads (the Flutter surface is re-created), then continues normally. It does not crash — the engine appears to fall back after the failed allocation. On older Motorola devices the same app launches with no reload.
Disabling Impeller completely resolves it. With this in
AndroidManifest.xml:the launch reload is gone and the app renders normally (OpenGL/Skia backend). Re-enabling Impeller (the default) brings the reload back. This points at the Vulkan/Impeller allocation path rather than anything app-side.

Another data point, with an axis that I don't think is represented in this thread yet: Android 16 on MediaTek/Mali, not Adreno.
Production app, Flutter 3.44.4, Impeller + Vulkan. 353 events / 117 users in the last 30 days on the top crash group alone.
Why the Android 16 correlation looks like a gate, not exposure
os99.2% of the crashes are on Android 16. Normalized against our own base, Android 16 accounts for 41.5% of all Android error events in this project over the same window (6,015 of 14,511) and 41.8% of affected users. Uniform distribution would predict ~146 events; we observe 350 — about 2.4x, with near-total exclusivity.
Devices
device.familyChipsets read from the events: MediaTek MT6855 / MT6855G (Mali-G57 class). One confirmed model: moto g56 5G, Android 16, kernel 6.12.38, 8 GB RAM.
This is consistent with @chinmaygarde's earlier point that the crash is not GPU vendor specific — every other report here is Adreno/Qualcomm, and we see the same signature on Mali.
Where it happens
~76% at cold start or in the first user flow. Our onboarding flow renders a Lottie animation, which matches the Lottie trigger discussed above.
Signature
The crashed thread tail matches what's already reported:
Our crash reporter groups by top frame, so this one bug is split across 9 groups for us (~378 events / 30d). Two of the sibling groups have cleaner semantic tails and are worth noting, since both are on the depth/stencil side of the same path:
The second one is a
FML_CHECKin the engine rather than a segfault, which is consistent with the "depth attachment unexpectedly missing from the EntityPass render target" chain described in #176211.On register dumps
I saw the request for register dumps upstream. Our reports come from a crash reporter that doesn't surface them in the API we have access to; if a raw crash payload from one of these Android 16 / MT6855 events would be useful, I can try to pull one — let me know what format helps most.
Happy to provide additional breakdowns (specific OS builds, memory state at crash time, more device models) if any of it is useful.
