WordPress站点Google Chrome浏览器滚动卡顿问题求助

Hey there, sorry to hear you're stuck with this weird scroll glitch—especially since the theme dev can't replicate it but you're seeing it consistently across 4 machines. Let's walk through targeted steps to narrow down the issue, tailored to Chrome's unique behavior:

Quick Chrome Settings Checks #

• Verify smooth scroll flag: Head to chrome://flags/#smooth-scrolling and make sure it's set to either Default or Enabled. Toggling this off/on and restarting Chrome often fixes odd scroll conflicts.
• Disable hardware acceleration: Chrome's hardware acceleration can cause rendering glitches with heavy pages. Go to chrome://settings/system, turn off "Use hardware acceleration when available", restart Chrome, and test scrolling again.
• Test in incognito mode: Load your merch page in Chrome incognito to rule out interference from browser extensions (like ad blockers or page modifiers) that might be messing with scroll behavior.

Page-Specific Code & Asset Checks #

• Temporarily disable custom scroll scripts: Open Chrome DevTools (F12), go to the Sources tab, and hunt for theme-related JS files handling scroll events (look for keywords like scroll, throttle, debounce). Disable these scripts one by one and test if the jumpy scroll goes away—this could point to a script conflict with Chrome's native scroll.
• Check for scroll-behavior: smooth conflicts: In the DevTools Elements tab, inspect the html or body element. If you see scroll-behavior: smooth applied, temporarily remove this style. Combining this CSS property with Chrome's native smooth scroll often causes single-scroll jumps after a delay.
• Audit for long tasks blocking the main thread: Since the issue hits after waiting a few seconds, it's likely tied to post-load assets (lazy-loaded images, third-party ads, analytics scripts). Use the DevTools Performance tab to record a session where you wait, then do a single scroll. Look for red "Long Task" bars—these block the browser from handling scroll smoothly.

Version & Environment Checks #

• Confirm Chrome versions across your machines: If all 4 computers run the exact same Chrome version, this could be a version-specific bug. Try updating Chrome to the latest stable release, or roll back to a previous version to see if the issue disappears.
• Check system-level scroll settings: On Windows, go to Settings > Accessibility > Visual effects and ensure "Smooth scrolling" is enabled. On Mac, check System Settings > Desktop & Dock > "Smooth scrolling"—even if all your machines use the same OS, a consistent misapplied system setting could be the culprit.

Hopefully one of these steps helps you pinpoint the root cause!
