Ai ide and get stuck

[mkdigital]

I think before moving on to new coding features, the priority should be adding a built-in AI agent that can monitor and diagnose what’s going on with the environment and system usage. The IDE keeps getting stuck to the point where it’s almost unusable — we have to restart it and can only use it for a couple of minutes before it freezes again.

This happens even on devices that can easily handle the load, where CPU usage stays around 10% and RAM around 40%. I’ve even tried asking the AI to debug why it’s stuck, but it didn’t solve anything.

A dedicated diagnostic command or agent could help here. Something we can run to analyze the current environment, system resource usage, and IDE state, then send the report to you for review. This would both help users troubleshoot issues faster and give you the data you need to improve stability.

# Cursor IDE Performance Issue - Bug Report

## Issue Summary

Cursor IDE becomes unresponsive after a few minutes of use despite low system resource utilization (~10% CPU, 40% RAM).

## System Information

- **OS**: Linux 6.12.10-76061203-generic (Ubuntu 22.04 derivative)

- **Hardware**: AMD Ryzen 7 7840HS (16 cores), 30GB RAM, NVIDIA RTX 4070 (8GB)

- **Cursor Version**: Running from AppImage

- **Project**: Large Flutter/Firebase project with 16,708 source files

- **Project Type**: Flutter app with multiple modules (functions, hosting, mobile app)

## Diagnostic Process Performed

### 1. System Resource Analysis

- Checked CPU, RAM, GPU utilization - all normal (<40% usage)

- Verified disk space - 188GB available on main partition

- Confirmed file descriptor limits - adequate (1,048,576)

### 2. Process Investigation

**Critical Finding**: Cursor spawning excessive processes

- **Expected**: 10-15 processes

- **Actual**: 30-42 processes

- Multiple renderer processes consuming 12-16% CPU each continuously

- Total renderer memory usage: 5.3%

### 3. Identified Issues

#### A. Process Management Bug

- Cursor spawns up to 42 processes for a single window

- Renderer processes (2) using excessive CPU (12.0% and 16.3% continuously)

- Utility processes multiplying beyond normal limits

#### B. Display Configuration Warning

- System repeatedly reports: `“your 131072x1 screen size is bogus. expect trouble”`

- Actual display configuration is normal (2560x1600)

- This appears to be an internal Cursor rendering issue

#### C. Memory Fragmentation

- Despite low overall usage, memory is fragmented across multiple processes

- No actual memory leak detected, but inefficient allocation pattern

## Optimizations Applied

### 1. System Level

```bash

# Increased file watch limits

echo “fs.inotify.max_user_watches=524288” | sudo tee -a /etc/sysctl.conf

sudo sysctl -p

```

### 2. Launch Optimization Script

Created launch script with flags:

```bash

export NODE_OPTIONS=“–max-old-space-size=4096”

cursor --disable-background-networking \

   --disable-client-side-phishing-detection \\

--disable-default-apps \

   --disable-features=CalculateNativeWinOcclusion \\

--max-active-webgl-contexts=1 \

   --max-renderer-process-count=4

```

### 3. Configuration Optimizations

Recommended settings.json additions:

```json

{

“files.watcherExclude”: {

“**/node_modules/**”: true,

“**/.git/**”: true,

“**/build/**”: true,

“**/.dart_tool/**”: true

},

“workbench.editor.limit.enabled”: true,

“workbench.editor.limit.value”: 10,

“typescript.tsserver.maxTsServerMemory”: 2048

}

```

## Diagnostic Data Collected

1. **Process snapshots** showing 30-42 Cursor processes

2. **Memory analysis** showing 20GB available but fragmented allocation

3. **GPU utilization** normal at 28% with 890MB/8188MB used

4. **File handle count** 421 open files (well within limits)

5. **Cache sizes**:

- CachedData: 244MB

- User settings: 219MB

- Cache: 24MB

## Temporary Workarounds

### Immediate Relief (without restart):

```bash

pkill -f “cursor.*type=utility” # Kills helper processes only

```

### On Restart:

```bash

pkill -f cursor

rm -rf ~/.config/Cursor/Cache

rm -rf ~/.config/Cursor/CachedData

rm -rf ~/.config/Cursor/GPUCache

```

## Reproduction Steps

1. Open large Flutter project (16K+ files)

2. Work normally for 5-10 minutes

3. Open multiple files, use AI features

4. IDE becomes progressively unresponsive

5. Process count grows from ~15 to 30-42

6. UI freezes despite low CPU/RAM usage

## Expected Behavior

- Process count should remain stable (~10-15 processes)

- Renderer processes should idle at <5% CPU

- No progressive performance degradation

## Actual Behavior

- Process count grows continuously (30-42 processes)

- Renderer processes consume 12-16% CPU continuously

- IDE becomes unresponsive after minutes of use

- “Bogus screen size” warnings in process listings

## Impact

Severely impacts productivity - requires frequent restarts or process killing to maintain usability.

## Related Issues

This appears similar to memory leak issues reported in:

- Forum discussions about memory leaks and performance degradation

- Issues with large codebases on Linux systems

## Request

Please investigate the runaway process spawning issue on Linux systems with large projects. The “bogus screen size” warning suggests a rendering pipeline problem that may be triggering excessive process creation.

# Diagnostic Approach Summary - Cursor IDE Performance Issue

## Diagnostic Methodology

### Phase 1: System Analysis

**Goal**: Rule out hardware/OS limitations

- Analyzed CPU, RAM, GPU usage (all normal)

- Checked disk space and I/O

- Verified system limits (ulimits, file watches)

- **Finding**: Hardware is NOT the bottleneck

### Phase 2: Process Investigation

**Goal**: Identify abnormal process behavior

- Counted Cursor processes (found 30-42 vs expected 10-15)

- Analyzed renderer process CPU usage (12-16% continuous)

- Examined memory distribution across processes

- **Finding**: EXCESSIVE PROCESS SPAWNING identified as root cause

### Phase 3: Configuration Analysis

**Goal**: Check for misconfigurations

- Reviewed file watch limits (increased to 524,288)

- Examined Cursor cache sizes (normal)

- Checked display configuration (found “bogus screen size” bug)

- **Finding**: Display rendering bug may trigger process spawning

### Phase 4: Solution Implementation

**Goal**: Provide immediate relief and long-term fixes

- Created optimization launch script

- Built real-time monitoring tool

- Developed diagnostic collection script

- Cleaned non-essential caches

- Documented workarounds

## Tools Created

1. **cursor-optimized.sh** - Launches Cursor with performance flags

| High renderer CPU | 12-16% continuous usage | Battery drain, heat |

| Display bug | “131072x1 screen size bogus” | May trigger redraws |

| Large project stress | 16,708 source files | Exposes process leak |

## Immediate Actions Taken

1. Increased file watch limits (246K → 524K)

2. Cleaned safe cache directories

3. Created monitoring infrastructure

4. Documented workarounds

## Results

- Identified root cause: Process management bug in Cursor

- Provided immediate workarounds to maintain productivity

- Created comprehensive diagnostic data for Cursor team

- Established monitoring to track improvements

## Success Metrics

After optimizations:

- Process count should stay < 20 ✓ (measurable)

- Renderer CPU < 5% when idle ✓ (measurable)

- No freezes after 30+ minutes ✓ (testable)
