It only seems to happen when the window is large, and when the command is executed soon after starting the recording

Demo: https://asciinema.org/a/3OiCukK9QIST6x1w5nSYihJGx
Here it works fine: https://asciinema.org/a/NWSQI94bKJKBfpi3XTqAg0e0g
Also seems to happen on an infinite loop, when doing:

for (;;) { ascii-image-converter FeelsDankMan.png -b --threshold 109 -W 30 | dotacat }

Demo for infinite loop: https://asciinema.org/a/cya0M11mhyfXfvKcXLqjj3ztJ

OS: Windows 10
Shell: PowerShell v7.3.0-preview.7
Terminal: alacritty 0.10.1 (2844606)

Even if there is no loop, it can still occur if this command is done early enough:

ascii-image-converter FeelsDankMan.png -b --threshold 109 -W 30 | dotacat
