bug(drawing): setting high refresh rate causes iTerm to struggle to process inputs

Bug report

• iTerm2 version: 3.4.22
• OS version: Sonoma 14.2.1
• Attach ~/Library/Preferences/com.googlecode.iterm2.plist
• Attach a debug log, if possible. com.googlecode.iterm2.plist
• Attach a screen capture video if it would make the reproduction steps clearer. Screen_Recording_2023-12-26_at_12.44.32_PM

Detailed steps to reproduce the problem

1. run yes in your shell
2. press control+c as fast as possible
3. note how as soon as you press control+c yes is stopped
4. set settings > advanced > drawing > When adaptive rendering and using the Metal renderer...max FPS to 120FPS
5. repeat steps 1-3

What happened

It takes many seconds for control+c to register and for yes to be stopped.

What should have happened

yes should have stopped instantly like it does at 30FPS
