S2 because the button disappears at the point of interaction, which might lead the user to believe it can no longer be interacted with.

The "Let's Go" button on the AI model selection screen is invisible in High Contrast mode because it uses a gradient background with border: none. In forced-colors mode, gradients are stripped, leaving the button with no visible boundary. Adding a ButtonText border ensures the button remains visible.

Hi @Chloe, this issue still occurs in our latest Nightly on Windows 10 with High contrast enabled and it also looks bad on Windows 11
