Impact Description

See #111145

Severe graphical artifacts on low DPR devices

Workaround

There is no work around.

Risk

low

Test Coverage

yes

Validation Steps

Build and run the example app in flutter/engine#35981 on a low DPR device.

Note: this is a request for a corresponding framework change, but both the engine and framework change need to be in the same release. The framework change is not risky, the engine change is riskier.

[itsjustkevin]

Merged in Flutter 3.3.2.
