Oh My Posh Right-hand Prompt Character Not Displayed

[cpplain]

I searched through discussions and issues but didn't find anything that looked relevant. I use Oh My Posh for my prompt and am seeing a strange issue with the prompt when using Ghostty. The rightmost character in the right hand prompt is missing. Everything is working as expected in my current day-to-day terminal, WezTerm.

In the screenshot below, you can see in the left window (WezTerm) there is a space (" ") used for padding following the execution time. In the right window (Ghostty), the space is not displayed.

I replaced the space with other characters and had the same result.

Ghostty config:

command = /opt/homebrew/bin/fish
font-family = "SF Mono"
font-size = 12
shell-integration = fish
theme = catppuccin-mocha
window-padding-x = 5
window-padding-y = 5
window-padding-balance = true

Oh My Posh config:

"$schema" = "https://raw.githubusercontent.com/JanDeDobbeleer/oh-my-posh/main/themes/schema.json"
version = 3
final_space = false

Should this be reported as an issue?

[mitchellh]

This is a bug in other terminal emulators and I'm unwilling to fix it because our behavior matches xterm: #884 I'm pretty sure this is what you're seeing?

[cpplain]

Yes, that does appear to be the same. Not sure why I didn't see this when searching. Thank you for the quick response.

For anyone who may find this discussion: adding a newline to the end of the right-hand prompt allows Ghostty to display the final character as expected.

template = " <b>{{ .FormattedMs }}</b> \n"
