Unicode characters rendered much slower than in Terminal.app
- iTerm2 version: Build 3.0.15
- OS version: El Captain 10.11.5 (15F34)
- Attach com.googlecode.iterm2.plist
- Sample file whose editing in Vim is slow with iTerm2 and fast with Terminal: https://github.com/zdharma/giturl/blob/301e0c5a9393900298b7b32fff022217f29a5111/lib/math_functions
Detailed steps to reproduce the problem:
- Download
math_functions
file - Run vim, 7.3 or 8.0
- Try to scroll down to hide the Unicode characters at top, see that scrolling is slow
- Searching across the Unicode-region, editing it - also slow
What happened: Slow Vim in iTerm2, fast in Terminal.app
What should have happened: Fast Vim in both terminals
