Description

I have a project which contains a ~400 MB raster tile. It takes a bit of time to zoom in/out and pan. The rendering status bar on the top keeps showing it is rendering.

Research direction

No source file, test, entry point, reproduction project, or target performance is identified. Start by reproducing zooming, panning, and rendering-status behavior with the reported roughly 400 MB raster MBTile project; done would require a demonstrated rendering improvement and a clear regression test or measurement.
