Title: [Windows][26.715.10079.0] Entire ChatGPT/Codex GUI flashes continuously

The entire new unified ChatGPT/Codex desktop GUI flashes rapidly and continuously immediately after launch, making the application unusable.

Environment:

• Package: OpenAI.Codex 26.715.10079.0
• Package full name: OpenAI.Codex_26.715.10079.0_x64__2p2nqsd0c76g0
• Windows: Windows 11, build 26200, x64
• Intel Iris Xe Graphics, driver 32.0.101.7085
• NVIDIA RTX 3000 Ada Generation Laptop GPU, driver 32.0.15.9595

Troubleshooting completed with no improvement:

• Uninstalled and reinstalled the application
• Terminated every ChatGPT/Codex process
• Used Windows App Repair
• Used Windows App Reset with a clean local profile
• Forced the application to Intel Iris Xe graphics
• Forced the application to NVIDIA graphics
• Disabled “Optimizations for windowed games”
• Launched the packaged executable directly with:

--disable-gpu
--disable-gpu-compositing
--disable-features=Vulkan

The application still flashes continuously even with GPU rendering and GPU compositing disabled. Closing the window can also leave approximately ten ChatGPT/Codex subprocesses running until the complete process group is forcibly ended.

Expected behavior:

The application should render normally and terminate its processes when closed.

Actual behavior:

The entire GUI flashes rapidly and continuously from startup, regardless of profile state or rendering configuration.

This began with the new unified ChatGPT/Codex desktop application. Please investigate as a Windows application regression. I can provide a phone video or screen recording if needed.

What steps can reproduce the bug?

Starting the codex app using any graphics configuration
