Description
- Your Hyper.app version is 3.4.1. Please verify you're using the latest Hyper.app version

- Any relevant information from devtools? (CMD+OPTION+I on macOS, CTRL+SHIFT+I elsewhere):
No
- Is the issue reproducible in vanilla Hyper.app?
Yes
Issue
Can't use ioctl to get the correct value of xpixel and ypixel:
let s = unsafe {
let s: winsize = std::mem::zeroed();
ioctl(STDOUT_FILENO, TIOCGWINSZ, &s);
s
};
dbg!(s.ws_col, s.ws_row, s.ws_xpixel, s.ws_ypixel);
There are both zero, which causes some apps don't work.

Research direction
The report names no source file or test entry point. Start by tracing Hyper's terminal resize handling on macOS and reproducing the ioctl behavior on darwin arm64 with the supplied Rust snippet; done means xpixel and ypixel return correct values and affected applications work.
