​
Zenocder Chat Appears White in JetBrains IDEs

​
Problem Description

Some users experience an issue where the Zencoder chat window in JetBrains IDEs (IntelliJ IDEA, PyCharm, WebStorm, etc.) appears completely white with no content displayed. This is internally known as the “White Screen of Death” (WSOD).

​
Symptoms

  • The Zencoder chat panel opens but displays only or partly a white screen
  • No error messages appear in the UI
  • The chat is usually completely non-responsive
  • The issue may persist across IDE being moved between different screens

​
Causes

This issue stems from how JCEF (Java Chromium Embedded Framework) is implemented in JetBrains IDEs. JCEF is a Java port of CEF (Chromium Embedded Framework) that JetBrains uses to render web content within their IDEs. In specific cases, particularly when rendering WebView content like the Zencoder chat interface, rendering issues can occur that result in the white screen.

​
Solutions

​
Option 1: Update to JetBrains 2025.2 EAP

JetBrains has recently released EAP 6 for their 2025.2 version of IDEs, which includes fixes for JCEF-related issues.

If your organization allows the use of Early Access Program (EAP) versions, this is the recommended solution.

  1. Download and install the latest EAP version from the JetBrains website
  2. Restart your IDE
  3. The Zencoder chat should now display correctly

EAP versions are pre-release software and may contain bugs or instabilities. If your organization has strict software policies, you may need to wait for the official 2025.2 release.

​
Option 2: Disable Out-of-Process JCEF (Workaround)

If you cannot use the EAP version, you can apply this workaround by modifying your IDE’s VM options:

  1. In your JetBrains IDE, go to Help > Edit Custom VM Options…
  2. Add the following line to the end of the file:
-Dide.browser.jcef.out-of-process.enabled=false
  1. Save the file
  2. Restart your IDE completely
  3. The Zencoder chat should now display correctly
