研究方向
從 FE-WMS 儲存庫中連結的 Storybook 重現開始，使用 @tanstack/virtual 3.13.5 比較瀏覽器縮放比例為 100% 與 90% 和 110% 時的捲動效果。調查虛擬清單周圍回報的測量和版面配置行為，然後驗證在這三個縮放級別下捲動是否都流暢且一致。

Describe the bug
🐛 Bug: Scroll lag / stutter when page zoom is exactly 100%
Description
When using @tanstack/virtual, scrolling becomes noticeably laggy/stuttery if the browser page zoom is set to 100% (default).
Interestingly, the issue disappears and scrolling becomes smooth again when changing the page zoom to 90% or 110%.
This behavior is consistently reproducible and seems to be tied specifically to the 100% zoom level.
🔁 Steps to Reproduce
- Open an app/page that uses
@tanstack/virtual - Set browser zoom to 100%
- Scroll the virtualized list
→ Observe scroll lag / stuttering - Change browser zoom to 90% or 110%
- Scroll again
→ Scrolling becomes smooth
✅ Expected Behavior
Scrolling should be smooth and consistent regardless of browser zoom level (including the default 100%).
❌ Actual Behavior
Scrolling is laggy only when zoom is exactly 100%.
Non-100% zoom levels do not show the issue.
🧠 Additional Notes / Observations
-
This may be related to:
- sub-pixel rounding
- layout measurements using fractional values
getBoundingClientRect,offsetHeight, orResizeObserverbehavior at 100% zoom
-
The issue occurs even on high-performance machines
-
The problem feels like repeated re-layout or recalculation during scroll
