[impeller] app crashes when drawing some raw vertices with custom shader or gradient shader

Steps to reproduce

Use canvas.drawVertices with custom shader set as Paint()..shader = ....

Use LinearGradient to experiance constant crash with Impeller (works with Skia)
Use custom shader (.frag file), then some geometries works fine, but some will lead to crash.

Using demo repository, steps to reproduce are:

Click "Show gradient" to get crash because of LinearGradient shader usage
Click "Show custom shader" - notice no crash yet. Then click "Show Circles" to get the crash.

Expected results

The app should not crash, or it should show an exception with the meaningful message if that's a user issue (like incorrect/unsupported geometry)

Actual results

Flutter 3.27.4 (stable):
The app crashes when using either LinearGradient or custom shader.
The app doesn't crash and draws correctly when using ImageShader

Flutter 3.29.0-1.0.pre.312 (master)
Flutter 3.29.0-0.3.pre (beta).
The app crashes when using LinearGradient.
When using custom shader, the app doesn't crash, but also doesn't draw as expected. Instead it shows in console:

[ERROR:flutter/impeller/entity/contents/vertices_contents.cc(117)] Break on 'ImpellerValidationBreak' to inspect point of failure: Missing texture for VerticesSimpleBlendContents

The app doesn't crash and draws correctly when using ImageShader

--
All cases from above works fine using Skia.
All cases were tested on macos (m3max macbook) and android (samsung galaxy tab s9) - the behavior is the same.

Code sample

I've created a GitHub repo to show the issue: https://github.com/alexgarbarev/flutter_shader_issues_demo

Screenshots / Video demonstration

This is a demo of the crash:

This is expected behavior (recorded using Skia):

I've not been able to reproduce the crash on the latest master or stable 3.27.4 with or without impeller targeting macOS. Am I missing something?

@maheshj01

@maheshj01 based on your video It looks like it's been recorded using Skia. (I'm judging based on how "color" looks like).
Skia:

Impeller 3.27.4:

Impeller 3.24.5

Could you please double check with command flutter run -d macos --enable-impeller

@alexgarbarev

Ah I see, Thanks for the details @alexgarbarev, I was running without the --enable-impeller Assuming impeller was enabled by default but thats only for Android and IOS.

Reproducible on latest stable and the master channel. With Impeller enabled the app crashes (Android, IOS, MacOS) and runs fine on Skia

══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
The following assertion was thrown during layout:
A RenderFlex overflowed by 194 pixels on the right.

The relevant error-causing widget was:
  AppBar AppBar:file:///Users/mahesh/Development/Triage/sample_app/lib/main.dart:53:25

To inspect this widget in Flutter DevTools, visit:
http://127.0.0.1:9101/#/inspector?uri=http%3A%2F%2F127.0.0.1%3A62399%2FEbNKhBxsSGc%3D%2F&inspectorRef=inspector-0

The overflowing RenderFlex has an orientation of Axis.horizontal.
The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and
black striped pattern. This is usually caused by the contents being too big for the RenderFlex.
Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the
RenderFlex to fit within the available space instead of being sized to their natural size.
This is considered an error condition because it indicates that there is content that cannot be
seen. If the content is legitimately bigger than the available space, consider clipping it with a
ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex,
like a ListView.
The specific RenderFlex in question is: RenderFlex#a9cb8 relayoutBoundary=up13 OVERFLOWING:

Looked at the example of a drawVertices using a LinearGradient.

The begin and end parameters of the LinearGradient result in begin and end points that have the same horizontal coordinate. So Paint::CreateContents calls Contents::SetColorSourceSize with an empty size.

The lazy texture function in Canvas::DrawVertices is then unable to create a snapshot based on the empty size. DrawVertices then crashes when trying to get the texture from the null snapshot.

This works if I patch Paint::CreateContents to skip the SetColorSourceSize call if the size is empty.

The "Show custom shader"/"Show circles" issue is similar.

In that case the src_contents in Canvas::DrawVertices does not have a color source size. So DrawVertices uses the texture coordinate coverage as the size of the snapshot.

The example app's makeCircleVertices specifies all of the texture coordinates as (0, 0) or (0, 25). So the texture coordinate coverage rectangle has no width, and the lazy texture function can not create a snapshot for that empty size.

Thank you @jason-simmons for quick response, investigation and fix!
Yes, texture coordinates might not be right here.

Some background: I'm doing a drawing app, where user can draw custom shapes with a stylus, and sometimes that input generates empty width segments (for example when input points are much closer than line width).
I used ImageShader before, and it worked fine, but in 3.27 it becomes broken - aliased (see screenshot from above). But it looks like that aliasing issue was fixed 3.29!

Out of curiosity, my question is: does it makes much difference (in performance and efficiency) if I generate image with ImageShader manually (for each scale/pixel ratio to guarantee 1.5 physical pixels width for aa smoothing), or if I specify GradientShader or own custom shader?
I thought initially that custom shader is applied to geometry directly (so I could just change scale/pixel ratio uniforms when user changes zoom, without texture re-generation), but based on your comments it seems to me that it used to generate a texture that then would be applied to geometry.
