Debugging UI Glitches in Developer Tools

A QA Case Study on IntelliJ IDEA's Nx Console Plugin

"Quality is not only about catching bugs but about enhancing every user’s interaction — even for developers." – Jubair Rahman

Introduction

While most QA engineers focus on end-user applications, we often overlook developer tools — which are also user interfaces that deserve attention. In this case study, I explore a real-world UI rendering issue in the Nx Console Plugin for IntelliJ IDEA, sharing how I investigated, documented, and contributed back to the community.


The Bug at a Glance

While using the Nx Console plugin in IntelliJ, I noticed that the action buttons (e.g., run, graph, extract-i18n, etc.) under each project target were visually overlapping and misaligned.

Usability Impact:

  • Difficult to click specific buttons
  • Reduced visual clarity
  • Affected Developer Experience (DX)

Screenshots

  • Overlapping Target Buttons


 


  • Misalignment of Icons


 


These issues, though minor at a glance, negatively impact usability and workflow efficiency.


Steps to Reproduce

  1. Open a project with Nx workspace in IntelliJ IDEA.
  2. Ensure Nx Console Plugin is installed and enabled.
  3. Navigate to the Nx Console panel.
  4. Select any project → go to Targets.
  5. Observe the layout of action buttons.

Test Strategy Summary

A combination of exploratory and visual testing was applied:

  • UI Testing: Checked layout, spacing, and alignment
  • Exploratory Testing: Navigated across features and settings
  • Visual Regression: Compared with VS Code’s Nx Console behavior

Metrics Tracked:

  • Number of affected targets
  • Frequency of glitches across themes
  • Interaction consistency

Test Plan Highlights

Objective:

Validate UI layout of the Nx Console Plugin in IntelliJ IDEA.

Scope:

✅ UI rendering and layout

❌ Target functionality logic

Tools Used:

  • IntelliJ IDEA 2023+
  • Nx Console Plugin (latest)
  • Windows 10/11

Deliverables:

Screenshots, test plan, test cases, GitHub repo

Root Cause Hypothesis

Potential causes may include:

  • DPI scaling or font rendering inconsistencies
  • Static layout design in plugin code
  • Lack of responsive/adaptive rendering logic

Workarounds Explored

  • Resize Nx Console panel to trigger a refresh
  • Reset zoom: Ctrl + 0
  • Use VS Code for smoother plugin rendering
  • Reported issue to Nx Console GitHub tracker

Final Thoughts

QA isn’t just about functionality — it’s also about ensuring intuitive, frustration-free UI, even in internal or developer-facing tools.

Visual bugs, when left unaddressed, degrade both trust and efficiency.
