Flickering when window is not on focus

[gtirloni]

If I run something like ollama run ... which has a progress bar when it's downloading a model, it looks fine if the window is focused but if another window is on top (but I can see ghostty's window behind), the last line that's updating starts flickering. If I focus the ghostty window again, the flickering stops.

Ghostty 1.1.0 (build 9283)
macOS 15.3

config:

window-height = 50
window-width = 220
