[Impeller] Respect max supported texture size when allocating glyph atlas texture. #45992
Conversation
…tlas texture. The earlier limit of 4096u was pessimistically small on some backends and too big on others (like older versions of OpenGL ES). The former would stop glpyhs from rendering when they got sufficiently large or numerous. The latter would cause errors on texture allocation. The full fix is tracked in flutter/flutter#133092

It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption to this rule, contact Hixie or stuartmorgan on the #hackers channel in Chat (don't just cc them here, they won't see it! Use Discord!). If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. |

Drive-by workaround for flutter/flutter#134292 |

- Can we have a test for this? i.e. something in typopgrapher that creates glyphs of a known size closer to the max texture limit or something?
Or a test that adds glyphs until it fails and checks that the size is the max texture limit?
- Did you verify this fixes the linked issue? This will definitely improve things but I'm not sure if we also need to do @bdero 's fix for multiple atlas textures.

Yeah, this improves things but I am more worried about the OpenGL backend where the min size is lower. Instead of not rendering more glyphs, I believe not being able to allocate the texture will lead to rasterizer teardown. Just wanted to get ahead of this badness. @bdero fix is definitely necessary. This just prevents the teardown on OpenGL ES and improves things on Metal. We can add the testing there as this will interact with typography and capabilities and will be reworked soon hopefully. |

Change LGTM.
We could probably capture this in a Metal golden by trying to render a bunch of big emojis on Metal -- that'd trip a validation failure past the 4096 limit when is this change isn't present. That being said, that would be a somewhat lousy test due to the environment dependence. We'd really need a fake/mock context to bake this behavior down into a reliable test.
Maybe the fact that our existing text goldens continue not breaking is OK for now.

Oh nice, I didn't realize we had this yet.

Can you also add this change to the STB backend? It's similarly pinned to an arbitrary texture size.

Oh, my bad. Didn't notice this call to action. Filing a followup.

Has this made it into a stable release of Flutter yet? I am trying to determine if the issue I'm seeing in Fintasys/emoji_picker_flutter#159 may be mitigated by this change, or if there is still an issue. Can we count on |
