Cause

Two Windows environments reported that with system WebView2 Evergreen `153.0.4234.32`, clicking buttons, menus, or settings in the CC Switch main interface causes flashing. Switching to WebView2 `152.0.4191.62` Fixed Version restored smooth operation. Reports cover Intel and AMD graphics cards, different Windows versions, and installation forms.

The existing issues do not yet include a maintainer-confirmed root cause or official fix. The reporter tested `--disable-gpu`, `--disable-features=CalculateNativeWinOcclusion`, `--disable-direct-composition`, `--use-angle=d3d11on12`, and `--disable-gpu-compositing`; none resolved the issue.

Fix

1. 1

   Extract WebView2 `152.0.4191.62` Fixed Version, then set `WEBVIEW2_BROWSER_EXECUTABLE_FOLDER` only for the current PowerShell session used to start CC Switch.

2. 2

   Start CC Switch and confirm that clicking any button no longer causes flashing.

FAQ

Is this caused by a fade-in/fade-out animation?

The existing issues do not confirm whether animation is the cause. Comments only provide a script to temporarily disable animation and do not report whether it resolves the flashing.
