Project: QGIS
Version: 3.34
When using "Refresh Layer at Interval" on vector layers, previous versions of QGIS would simply redraw the layer (for animations etc.), without refreshing data from the data source.
A new widget is provided which allows users to select the layer refresh options according to their preferred use case:
- "Reload Data": The layer will be completely refreshed. Any cached data will be discarded and re-fetched from the provider. This mode may result in slower map refreshes.
- "Redraw Layer Only": This mode is useful for animations or when the layer style should be updated at regular intervals. Canvas updates are deferred in order to avoid refreshing multiple times if more than one layer has an automatic update interval set.
