[Bug] [carto] RasterTileLayer renders in corner of canvas

[donmccurdy]

Description

Under some configurations I'm seeing the RasterTileLayer render its contents in the lower-left corner of the canvas:

In this screenshot, the black pixels should be over the lake.

Flavors

• Script tag
• React
• Python/Jupyter notebook

Steps to Reproduce

https://stackblitz.com/edit/carto-raster-pixelratio

1. assign canvas width and height to a fixed value (e.g. 512px)
2. assign RasterTileLayer#tileSize (maybe? it seemed like this mattered in my early tests, maybe not)
3. compare with devicePixelRatio = 1 vs. devicePixelRatio > 1

The problem occurs only for devicePixelRatio > 1 in my testing. An easy way to switch back and forth would be to create a custom 'device' in Chrome dev tools, with a different devicePixelRatio:

Environment

• Framework version: deck.gl 9.0.40
