Flickering issue

[Blushyes]

I noticed that in the current rendering process, when the canvas detects differences, it directly clears the entire canvas, which causes a flickering issue. For example, in the example form, when the input changes, the whole interface flickers. This creates a poor user experience. Is there any way we can fix this?

Thanks for opening the issue! Which OS / terminal are you using? For me there's no noticeable flickering, but this might just be a very environment-dependent issue. There are some optimizations that can probably be made if I can reliably reproduce the issue.

Thanks for the quick reply. I’m using macOS M2, system version 15.5 (24F74), and my terminal is oh-my-zsh.

Thanks! I'll have to put together an environment that reproduces this before I can really tackle it myself.

One thing that might help in the meantime is to make sure you're compiling with release optimizations. I don't really expect it to change much, but it might make some difference.

Could it be related to ghostty-org/ghostty#8176

@Blushyes could you try latest development version? We shipped per-row diffing.
