Attempted a real reproduction on macOS (Chromium via Playwright, light theme matching the report, MySQL connection, ~150 SQL lines exceeding the viewport, rapid mouse-wheel scroll to bottom then immediately back to top matching the described steps).

Sampled the .cm-cursor-primary element's computed border-left-color / opacity / visibility at animation-frame resolution (~357 samples across the scroll gesture + 3s settle) — the cursor stayed black, opacity 1, visible throughout, never turned white or invisible. Also checked the editor theme code (editorThemes.ts) and the default vscode-light CodeMirror theme — cursor color is a static opaque #000, no dynamic logic that could make it blend into a white background.

The report is on Windows 10 desktop (WebView2 rendering). Since I can't reproduce this on macOS/Chromium, this looks like it may be a platform/GPU-compositor-specific rendering glitch (similar pattern to #6709) rather than a logic bug reachable from the code. Not comfortable guessing a fix without real evidence.

验证了，是自己电脑的问题，非工具本身问题。
