trying to render emojis causes system freeze

[dvc94ch]

hard to provide a reproducer as I've modified stuff in different places. also it would be bordering on distributing malware. any suggestions how to debug a system freeze?

It's very hard to diagnose. Can you say more about what you're running it on?

I do have one place I'm seeing GPU timeouts, which is #139. I started digging into it but have put it on the back burner for now.

so made sure that the thing panics before rendering to avoid system freezes. seems like the problem is that the glyph only provides a bitmap and no outlines which isn't handled and then causes a ctx.fill_glyph without a glyph being encoded. Letting make_path return None doesn't render the emoji, but it prevents a freeze.

next question would be, how to go about rendering the bitmap?

There is FillImage support in the shaders, but the CPU-side support for it is currently missing. I will add it, but no guarantees when.

Since this issue was opened, we've migrated to wgpu (in #193)

I think things are likely to be different enough since then, and since no reproduction was reached, I'm going to close this out.
