<!-- Answer --> This isn't a documented or widely reported issue for Safari on iPad, but there are known limitations with Superset's chart image export. Superset uses libraries like `dom-to-image-more` for some chart types, which only capture what's visible in the DOM, and ECharts' export API for others. Blank image downloads have been seen before (on Chrome) due to canvas rendering issues, and a fix was merged in Superset master to preserve canvas content during export—though there's no explicit Safari/iPad-specific handling in the code or docs ([reference](https://github.com/apache/superset/issues/36534)). If you're still seeing blank images, try making sure the chart is fully rendered before exporting, check the browser console for errors, and test with other chart types or browsers. If possible, try updating to the latest Superset version to see if recent fixes help. If the problem persists, gathering browser console logs and Superset logs will help diagnose further. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
