Looks like Skia is trying to upload a texture that the driver doesn't like. Trying to reproduce. |

Hi, I'm seeing the same trace in the Hamilton app and we're getting unpredictable crashes on iOS (need to test Android). I'll add to the issue when I get more information.
|
|
FYI this is a blocker to the release of an important new feature for Hamilton app. |

I am able to reproduce this. Stack trace was similar on the GPU thread. Frame variable on the call to Stack Trace: |

Hi, I am a developer of this app which uses flutter https://itunes.apple.com/gb/app/cluttr/id1316324348?mt=8 I have noticed this problem too. The crash occurs only on ios release mode. It works fine on android and in debug mode for ios. Couldn't make much sense of Xcode error so I've attached a screenshot. (ignore console log)

Hi! Thanks for all the info. I've reproduced this crash, and we're 95% sure it's a driver bug. I've filed a report with Apple to fix their driver issue, and we're currently putting a workaround into Skia: https://skia-review.googlesource.com/c/skia/+/125729 There is a potential performance impact to the workaround, however - so we'll be monitoring that, and we could use a more complex workaround if necessary. |

@brianosman how soon will those changes be reflected in flutter master branch? |
|
It's landed in the flutter engine repo, someone from the flutter team (@chinmaygarde ) would have to comment on when that's going to show up in flutter master. |
|
The last engine roll 16 hours ago was too early to pick up this change. I'll attempt another roll later today and update this ticket. Thanks for the fix @brianosman. |
|
Hi @chinmaygarde is this fix in? |
|
Actually fixed in #17362 |

This still seems to be happening in version 1.9.1

@zw1924 @SundayMan The two crashes that you've attached look similar to the original crash from this bug report, but they're definitely different. It looks like the driver is crashing in a slightly different way (and in response to a different usage pattern). If you could create a new issue with steps to reproduce the crash(es) you're seeing, that would be helpful. |

Steps to Reproduce
Got the stack trace below from iOS profile build for iPod Touch (iOS 11.3) by entering (or maybe trying to leave) the Flutter Gallery Typography section. I could not find a way to reproduce.
