PLEASE ATTACH YOUR PLIST FILE FOR BUG REPORTS! Seriously! I'll probably ask you for it if you don’t.
Detailed steps to reproduce the problem:
- Open up Iterm2
- Open some tabs with Vim running
- Wait for random freezes to happen with no observable pattern
What happened:
- Existing tabs in Iterm2 freeze
- I can still open new tabs and they work. However, they all have black background.
- If I open a new window of Iterm2, it works perfectly, but the old window remains the same.
-
htop
shows CPU usage of Iterm2 to be ~90%.
What should have happened:
- Existing tabs shouldn't freeze randomly (it has happened to me many times, I fail to see any pattern)
- New tabs in frozen window shouldn't have black background
