Codex App reportedly flashes nonstop on launch and becomes unusable

A Reddit user says the Codex App starts flashing nonstop immediately after launch and becomes impossible to use. - The window loads, but the UI flickers so badly that nothing can be clicked. - The poster suspects a recent update, GPU rendering issue, or UI bug. - The attached screenshot shows the app running on desktop, but the real problem is described as a screen-recorded flashing loop rather than a static rendering issue.
