Ghostty 1.4 speeds up text parsing 5.7x and compresses scrollback by 70-90%

Ghostty 1.4 is out with ASCII parsing boosted from 128 MB/s to 725 MB/s, scrollback compression cutting memory use by 70-90%, and a redesigned OpenGL pipeline for Linux and FreeBSD. The default scrollback limit rose from 10 MB to 50 MB per terminal, and animated images via the Kitty graphics protocol are now supported.

• ASCII parsing is 5.7x faster, rising from 128 MB/s to 725 MB/s
• Scrollback compression cuts memory 70-90%; limit raised to 50 MB
• New OpenGL pipeline uses EGL, DMABUF and triple buffering
• Requires GTK 4.18 and libadwaita 1.7, so Ubuntu 24.04 LTS is unsupported
