App crashes on any touch input on Ubuntu 20.04 LTS with Wayland mode #126

Closed lionelmennig closed 1 year ago

lionelmennig commented 2 years ago

First of all, thank you for your amazing work!

Steps to Reproduce

  1. Build and launch any Flutter app with flutter-elinux run on Wayland (Ubuntu 20.04 LTS)
  2. Touch the screen
  3. App crashes

Error message

[FATAL:flutter/lib/ui/window/pointer_data_packet_converter.ccc(188)] Check failed: iter != states_.end().

Additional infos

This crash won't occur with classic Linux build of the same app, and I can reproduce it with the Flutter demo app (Counter app).

Thank you for your help!

Can you please put the whole log message?

Did you use Weston?

HidenoriMatsubayashi commented 2 years ago

X86_64 or arm64?

lionelmennig commented 2 years ago

@HidenoriMatsubayashi

  1. Weston was not installed
  2. x64

Indeed, installing Weston and running the app in this context won't crash on touch, which basically is a fix for my issue. Thank you, I should've tried that before.

Still, I'm not sure.

What kind of Wayland compositor do you use?

lionelmennig commented 2 years ago

I simply used to log in Ubuntu with Wayland mode (from the cogs menu on launch screen), and since the title bar of my app was looking different when built with eLinux against default Linux, I thought it was sufficient to consider being in a Wayland context window.

HidenoriMatsubayashi commented 2 years ago

Understood. Thanks, but I have never seen this error message/crash.

lionelmennig commented 2 years ago

Can I provide you anything to help you out about this? The only error message I get in the console is the one I shared, is there any place I can find more details about the crash?

HidenoriMatsubayashi commented 2 years ago

Can you please try the following commands and get the log messages?

$ flutter-elinux build elinux --debug
$ FLUTTER_LOG_LEVELS=TRACE ./build/elinux/<target_arch_name>/debug/bundle/<appname> -b .

I think you might be interested by this one, occuring with the build command:

Sorry for no updates for a long time. But I was able to reproduce this issue and made a change. https://github.com/sony/flutter-embedded-linux/pull/371 will fix it. Thank you.
