This seems a suspicious. How do you measure the CPU load of Ghostty? Is the measure/reporting method just attributing the cpu load of the commands/programs you're running in Ghostty to Ghostty?
You could test this by running "yes > /dev/null" in Ghostty. In Activity Monitor on my Macbook it shows `yes` using 100% and Ghostty using 0.5% of cpu.
