Black tiles with DataTileSource and WebGLTileLayer

See original GitHub issue

Describe the bug

Theol.layer.WebGLTile doesn’t render data that were loaded with ol.source.DataTile using a custom tile grid:

Extent: [0, -23828, 23903, 0] Sizes: [[1, 1], [7, 7], [ 25, 25 ], [100, 100]] Tile sizes: [[770, 768], [240, 240], [240, 240], [240, 240]]

The following warning message gets logged:

WebGL warning: texImage: Desired upload requires more data than is available: (767 rows plus 770 pixels needed, 767 rows plus 258 pixels available)

I didn’t previously experience this issue and wonder whether it may be due to either https://github.com/openlayers/openlayers/pull/11532 or https://github.com/openlayers/openlayers/pull/12024.

Expected behavior

Not sure whether this is a bug or whether my understanding of the tile grid is wrong.

That option appears to be used only for defining styles. An unpackAlignment option (with default of 1?) would be useful to ensure the calculation of bandCount for TileTexture corresponds to the gl.pixelStorei setting.

@mike-000 It works!
