[Impeller] Simple program on Android Vulkan backend fails to release graphics memory, eventually crashes #131001
Description
import 'dart:math' as math;
import 'dart:ui';
Color randomColor([double opacity = 1.0]) =>
Color((math.Random().nextDouble() * 0xFFFFFF).toInt()).withOpacity(opacity);
void main() async {
window.onBeginFrame = (_) {
final recorder = PictureRecorder();
final canvas = Canvas(recorder);
canvas.drawPaint(Paint()..color = randomColor());
canvas.drawRect(
const Rect.fromLTWH(200, 200, 300, 300),
Paint()..color = randomColor(.5),
);
final picture = recorder.endRecording();
final builder = SceneBuilder();
builder.addPicture(Offset.zero, picture);
final scene = builder.build();
window.render(scene);
scene.dispose();
picture.dispose();
window.scheduleFrame();
};
window.scheduleFrame();
}Run this on a Pixel 7 pro for a minute or so and eventually:
E/flutter (10821): [ERROR:flutter/impeller/base/validation.cc(49)] Break on 'ImpellerValidationBreak' to inspect point of failure: Failed to encode and submit command buffer while ending render pass.
E/flutter (10821): [ERROR:flutter/impeller/base/validation.cc(49)] Break on 'ImpellerValidationBreak' to inspect point of failure: Failed to encode and submit command buffer while ending render pass.
And the app stops rendering.
