[BUG] --logo-type iterm image renders briefly then disappears after v2.64.0 logo printing rewrite

• I have checked the FAQ but the issue is not covered

Description

fastfetch version: 2.64.0 / 2.64.1 (regression from 2.63.1) System: macOS Tahoe 26.5.1, Apple M1 Terminal: iTerm2 (TERM_PROGRAM=iTerm.app)

Description: After the v2.64.0 logo printing rewrite ("Reworks the built-in logo printing logic"), --logo-type iterm no longer works correctly. The image flashes briefly (the iTerm2 escape sequence is sent and rendered) but is immediately overwritten/disappears, suggesting the cursor positioning or screen clearing after the image output is incorrect.

Steps to reproduce:

fastfetch --logo-type iterm --logo-padding-top 8 --logo-padding-left 3 --logo-padding-right 3 --logo-width 40 --logo-height 21 --logo-preserve-aspect-ratio true --logo ~/logos/some-image.png -c ~/.config/fastfetch/config.jsonc
Expected: Image renders and stays visible alongside system info modules (worked in 2.63.1).

Actual: Image appears momentarily (≈1 frame), then vanishes. Adding --pipe false and --show-errors produces no error output but the image still disappears.

Impact: Blocks iTerm2 users on macOS from using image logos on shell startup. Pin to 2.63.1 works around the issue.

This is based on example template 25.jsonc

I have a number of different logos that are cycled and managed using shell logic.  The call to produce the image and fastfetch is:-

fast fetch --logo-type iterm --logo-padding-top 8 --logo-padding-left 3 --logo-padding-right 3 --logo-width 40 --logo-height 21 --logo-preserve-aspect-ratio true --logo "$imageName" -c ~/.config/fastfetch/my.jsonc

Facing same with Foot terminal with Fish shell + sixel image:

Image converted using chafa --format=sixel -s 24x12 Grub_1.png > Grub_1.six

config:

{   
    "$schema": "https://github.com/fastfetch-cli/fastfetch/raw/dev/doc/json_schema.json",
    "logo": {
        "type":"raw",
        "source": "/home/itachi/.config/fastfetch/assets/Grub_1.six",
        "width": 22,
        "height": 13,
        "padding": {
            "top": 1,
            "left": 1,
            "right": 1
        }
    }, }

This use to work perfectly until a week ago.
