Description

Continue opens with only the top toolbar visible.

The entire main panel is completely black and unresponsive.

There is no loading screen, no sign-in page, no model selector, and no error message.

To reproduce

• Reinstalled Continue
• Disabled all other third-party plugins
• Restarted CLion
• JCEF is enabled
• No relevant exceptions appear in idea.log

Log output

The exact same Continue configuration works correctly in:

- IntelliJ IDEA 2026.2
- PyCharm 2026.2

Only CLion shows this issue.
(Attach the black screen screenshot)

No source file or test is named. Start by reproducing the black panel in CLion 2026.2 with Continue v1.0.67, then compare its behavior and idea.log with IntelliJ IDEA and PyCharm, where the same configuration works. Done means the Continue panel renders and responds in CLion without regressing those working IDEs.
