I've heard various things about VTE over the years including:
1. They "like" xterm because i get value out of screen tearing and feeling like they can catch what is scrolling by (even though it's literally seconds slower)
2. They don't like the 40 fps cap it currently has because it predates reliable access to vertical sync information in applications.
3. They are using the GTK 4 port which draws with cairo and uploads surface data on every frame update.
The patches I put together for VTE this week (while having some down time with Covid) address a portion of that by making it render fonts/rectangles/emoji/etc on the GPU using GTK's OpenGL renderer (which I also wrote a large portion of).
