Should be fixed by #1532, no? |
|
Nope, these images are with #1532 applied. |

For reference, this is where the tile boundaries are, it looks like the rendering errors are independent of the tile boundaries.

Narrowing down this test failure: It never happens when only one tile is being displayed, and it also doesn't happen when reducing the worker count to 1, so the error seems to be somewhere in concurrent tile parsing. |

For now, the buckets depending on Glyphs that are not yet available are simply not created (or created and discarded). In the future we could refactor the code to not create the bucket at all or put the bucket in a suspended state until the glyph range is available.

What happened was that the Glyph PBF was marked as parsed before all of the glyphs were inserted into the FontStack. That means some labels (always at the beginning) were missing some letters because they couldn't be found when calculating the shaping. |
