Safari handles canvas rendering differently compared to Chrome and Edge, which is why the feature works correctly in those browsers. To address this issue, you can consider using Playwright as an alternative for capturing screenshots. Playwright offers better compatibility with modern web standards, including Safari. You can enable the `PLAYWRIGHT_REPORTS_AND_THUMBNAILS` feature flag in Superset to switch from Selenium to Playwright for generating reports and thumbnails. This might improve the compatibility of the "Download As Image" feature with Safari. To enable this feature flag, add the following configuration to your `superset_config.py`: ```python FEATURE_FLAGS = { "PLAYWRIGHT_REPORTS_AND_THUMBNAILS": True, } ``` This configuration will enable Playwright for generating reports and thumbnails, potentially resolving the issue with empty images in Safari <sup>[[1]](https://github.com/apache/superset/blob/master/superset/config.py)</sup><sup>[[2]](https://github.com/apache/superset/blob/master/superset/utils/webdriver.py)</sup>. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* -- This is an automated message from the Apache Git Service.
