MacOS: Moving windows between monitors occasionally causes text display issues

[AMMullan]

This isn't a big issue but it's something I've noticed. When I move Ghostty from one window to another occasionally (about 1 in every 6-8 moves if I'm doing it continuously) the text rendering seems broken. It's a brand new Macbook and so quite clean and don't have issues with other apps.

Replication: Move Ghostty between windows

Notes

1. Clicking Ctrl or any other key seems to fix the issue weirdly enough.
2. I just noticed that the prompt_context() I have in my zshrc seems to change when the rendering defect happens. In the screenshots below you'll notice the broken icon is a rainbow but then after pressing Ctrl it changed back to the frog that it was for that zsh session.
3. Tested this on iTerm2 and can confirm that the defect doesn't occur in that.

Ah yeah, potentially! Didn't find that with a search so good spot 👏🏻

Happy to close this if it is related.

In fact, this definitely looks like #2731
