## Issue 1: Slow Performance
```
┌─────────────────────────────────────────────────────────────────┐
│ SYMPTOM: Terminal feels laggy or unresponsive │
├─────────────────────────────────────────────────────────────────┤
│ │
│ Possible causes: │
│ │
│ ┌─────────────────────────────────────────────────────────┐ │
│ │ Cause │ How to check │ │
│ │ ───────────────────────────────────────────────────── │ │
│ │ Too many tabs open │ Count your open tabs │ │
│ │ Large scrollback buffer │ Check settings │ │
│ │ Heavy program running │ Check Activity Monitor │ │
│ │ System low on memory │ Check memory usage │ │
│ └─────────────────────────────────────────────────────────┘ │
│ │
└─────────────────────────────────────────────────────────────────┘
```
### Solutions
```
┌─────────────────────────────────────────────────────────┐
│ SOLUTION: Reduce open tabs │
├─────────────────────────────────────────────────────────┤
│ │
│ Before: │
│ ┌───┬───┬───┬───┬───┬───┬───┬───┬───┬───┐ │
│ │ 1 │ 2 │ 3 │ 4 │ 5 │ 6 │ 7 │ 8 │ 9 │10 │ ← Too many │
│ └───┴───┴───┴───┴───┴───┴───┴───┴───┴───┘ │
│ │
│ After: │
│ ┌───┬───┬───┐ │
│ │ 1 │ 2 │ 3 │ ← Just what you need │
│ └───┴───┴───┘ │
│ │
│ Close tabs you're not actively using. │
│ │
└─────────────────────────────────────────────────────────┘
```
Reduce the scrollback limit in Settings:
```
┌─────────────────────────────────────────────────────────┐
│ │
│ Settings → Terminal → Scrollback │
│ │
│ Current: [100,000 lines] ← Very large │
│ │
│ Recommended: [10,000 lines] ← Good balance │
│ │
│ Minimal: [1,000 lines] ← Best performance │
│ │
└─────────────────────────────────────────────────────────┘
```
Check if your system has enough resources:
```
┌─────────────────────────────────────────────────────────┐
│ Check Activity Monitor (Mac) or Task Manager (Windows) │
├─────────────────────────────────────────────────────────┤
│ │
│ Memory usage: │
│ ████████████████████░░░░ 80% ← Might be too high │
│ │
│ If above 90%: │
│ • Close other applications │
│ • Restart your computer │
│ │
└─────────────────────────────────────────────────────────┘
```
***
## Issue 2: Display Problems
```
┌─────────────────────────────────────────────────────────────────┐
│ SYMPTOM: Text looks garbled, misaligned, or corrupted │
├─────────────────────────────────────────────────────────────────┤
│ │
│ What you might see: │
│ │
│ ┌─────────────────────────────────────────────────────────┐ │
│ │ ▒▒▒▒▒▒▒▒ │ │
│ │ █░█░█░█░ ← Garbage characters │ │
│ │ ████████ │ │
│ │ │ │
│ │ Helllo World ← Duplicated or missing characters │ │
│ │ He o Wor d │ │
│ │ │ │
│ │ Text here │ │
│ │ Text should be here ← Misaligned │ │
│ └─────────────────────────────────────────────────────────┘ │
│ │
└─────────────────────────────────────────────────────────────────┘
```
### Solutions
Type `clear` or press Ctrl+L
Type `reset` to fully reset the terminal
Close and reopen the tab
```
┌─────────────────────────────────────────────────────────────────┐
│ RESET COMMANDS │
├─────────────────────────────────────────────────────────────────┤
│ │
│ Command What it does │
│ ────────────────────────────────────────────────────────── │
│ │
│ clear Clears visible screen │
│ (scrollback preserved) │
│ │
│ reset Full terminal reset │
│ (clears everything, fixes most issues) │
│ │
│ Ctrl+L Same as clear (keyboard shortcut) │
│ │
└─────────────────────────────────────────────────────────────────┘
```
***
## Issue 3: Color Problems
```
┌─────────────────────────────────────────────────────────────────┐
│ SYMPTOM: Colors look wrong, washed out, or completely off │
├─────────────────────────────────────────────────────────────────┤
│ │
│ Expected: Actual: │
│ ┌─────────────────────┐ ┌─────────────────────┐ │
│ │ █ Red │ │ ░ Gray │ │
│ │ █ Green │ │ ░ Gray │ │
│ │ █ Blue │ vs │ ░ Gray │ │
│ │ █ Yellow │ │ ░ Gray │ │
│ └─────────────────────┘ └─────────────────────┘ │
│ │
└─────────────────────────────────────────────────────────────────┘
```
### Solutions
Your shell needs to know it's in a modern terminal:
```
┌─────────────────────────────────────────────────────────┐
│ Check current TERM value by typing: │
│ │
│ echo $TERM │
│ │
│ Should show: xterm-256color │
│ │
│ If it shows something else, add to your shell config: │
│ │
│ For ~/.zshrc or ~/.bashrc: │
│ export TERM=xterm-256color │
│ │
└─────────────────────────────────────────────────────────┘
```
```
┌─────────────────────────────────────────────────────────┐
│ CHECK FOR THEME CONFLICTS │
├─────────────────────────────────────────────────────────┤
│ │
│ If you have a custom theme in your shell: │
│ │
│ ┌───────────────────────────────────────────────────┐ │
│ │ Monolex Theme ←→ Shell Theme (Oh-My-Zsh, etc.) │ │
│ │ ↓ ↓ │ │
│ │ Sets colors Also sets colors │ │
│ │ ↓ ↓ │ │
│ │ CONFLICT! │ │
│ └───────────────────────────────────────────────────┘ │
│ │
│ Try temporarily disabling your shell theme │
│ to see if that's the cause. │
│ │
└─────────────────────────────────────────────────────────┘
```

## Issue 4: Scrolling Problems
```
┌─────────────────────────────────────────────────────────────────┐
│ SYMPTOM: Can't scroll, scroll jumps, or scroll is very slow │
├─────────────────────────────────────────────────────────────────┤
│ │
│ Types of scrolling issues: │
│ │
│ 1. Can't scroll at all │
│ └─▶ Terminal might be in alternate screen mode │
│ │
│ 2. Scroll position jumps around │
│ └─▶ Program might be fighting for scroll control │
│ │
│ 3. Very slow scrolling │
│ └─▶ Too much content in scrollback │
│ │
└─────────────────────────────────────────────────────────────────┘
```
### Solutions
Some programs (vim, less, man) use an alternate screen:
```
┌─────────────────────────────────────────────────────────┐
│ ALTERNATE SCREEN MODE │
├─────────────────────────────────────────────────────────┤
│ │
│ Normal terminal Alternate screen │
│ ┌─────────────────┐ ┌─────────────────┐ │
│ │ $ history │ │ vim file.txt │ │
│ │ $ ls │ │ ────────────────│ │
│ │ $ cd project │ │ Line 1 │ │
│ │ ... │ ←→ │ Line 2 │ │
│ │ (can scroll) │ │ (no scroll) │ │
│ └─────────────────┘ └─────────────────┘ │
│ │
│ To exit alternate screen: │
│ • Exit the program (q in vim/less/man) │
│ • Press Ctrl+C to interrupt │
│ │
└─────────────────────────────────────────────────────────┘
```
Reduce scrollback history:
```
┌─────────────────────────────────────────────────────────┐
│ │
│ More history = slower scrolling │
│ │
│ 100,000 lines: ████████████████████ (slow) │
│ 10,000 lines: ████ (normal) │
│ 1,000 lines: █ (fast) │
│ │
│ Adjust in Settings → Terminal → Scrollback │
│ │
└─────────────────────────────────────────────────────────┘
```
***
## Issue 5: App Compatibility
Some programs have special requirements:
```
┌─────────────────────────────────────────────────────────────────┐
│ APP-SPECIFIC TIPS │
├─────────────────────────────────────────────────────────────────┤
│ │
│ vim / neovim: │
│ ───────────── │
│ Add to your config: │
│ set termguicolors │
│ │
│ tmux: │
│ ───────────── │
│ Add to ~/.tmux.conf: │
│ set -g default-terminal "xterm-256color" │
│ │
│ htop / btop: │
│ ───────────── │
│ Should work out of the box. │
│ If colors look wrong, check TERM variable. │
│ │
│ SSH sessions: │
│ ───────────── │
│ Remote TERM might differ. Add to remote ~/.bashrc: │
│ export TERM=xterm-256color │
│ │
└─────────────────────────────────────────────────────────────────┘
```
