Terminal screen goes gibberish after wakeup from sleep on macOS

[mislam]

Here's the screenshot of the issue:

System config:

• Mac mini
• Chip: Apple M4
• Memory: 24GB
• macOS: Sequoia (15.2)

How to reproduce:

• On macOS, put your mac on sleep
• Wait few minutes
• Wake it up, and you see the terminal blanks out with the gibberish
• The gibberish will go away after 3-5 seconds

Here's my ~/.config/ghostty/config

font-family = FiraCode Nerd Font
font-size = 16
theme = catppuccin-mocha
mouse-hide-while-typing = true
background-opacity = 0.8
background-blur-radius = 20
window-padding-x = 10
window-padding-y = 10
shell-integration-features = no-cursor,no-sudo,title
macos-titlebar-proxy-icon = hidden

By the way, I tried with blank config file as well. Same problem remains.

I tried to lookup before posting this. Searched with screen, blank etc. Didn't find any. It thought it's just me. Anyhow, good luck!
