Simply enlarge the window, and the memory will increase exponentially.

I suspect that this is similar to https://github.com/slint-ui/slint/discussions/4079 , except for macOS. Could you try enabling the renderer-skia feature? That would flip to metal layering - I wonder if that reproduces it.

During the waiting period for a reply, I also noticed that with the increase in the number of conversation turns, the memory usage of the application increases rapidly. When I ask the LLM to “tell me a 1000-word story” three times, the memory usage directly increases by 60MB.

However, when I enable the renderer-skia feature, this issue basically disappears, and the memory usage only increases slightly with each conversation turn. But the memory change caused by zooming remains the same.

I mentioned in another issue that my application is an LLM client. Based on the information you provided, I conducted the above tests and obtained these results. The complete code can be found at dali.
