Terminal editor (neovim, helix, emacs --nw) not rendered correctly

[lukeflo]

Describe the bug I'm trying to create a vhs gif of my own bash-based TUI notes management system. So far, everything works fine. But when I open a note from inside a terminal-based editor, the background of the editor is not rendered correctly. I've tested it with neovim, helix and emacs in --no-window mode, its the same with all of them (see picture below).

Setup Please complete the following information along with version numbers, if applicable.

• OS: Void Linux 6.6.35_1
• Shell: zsh and bash
• Terminal Emulator: foot

To Reproduce Steps to reproduce the behavior (difficult because you had to clone my repo first):

1. Clone the mentioned repo and build notesbash
2. Setup a notes directory
3. Create a vhs tape which opens a file

Expected behavior I expect the produced GIF to show the editor window correctly with the background color spanning the whole "terminal" screen. In the screenshot below the color should not end directly next to the line numbers but reach to the outer margin of the window (left margin of the L in Loaded).
