It takes multiple seconds to launch, random lines disappear in the scroll back, it’s internal state gets messed up causing the TUI to show duplicate and/or offset lines, and it frequently causes some kind of GPU buffer corruption causing the entire terminal env to show garbage.
Yes, this is the ubiquitous memory issue that I mentioned. Unfortunately, it is now the baseline in all modern apps.

I haven't seen this issue, other than when I am using a shell that is bugged and does it with all TUI/console programs (usually a virtualized shell which I resized). Do you have a reproducible example of this?
The trick is not bringing React into the terminal.
(FWIW, I have a link to a TUI harness in my profile that uses 50MB of ram and about 1% CPU while streaming, even in giant contexts)
