求助：Mac版Chrome 65.0.3325.146正式版开发者工具移动端调试异常

Hey there, sorry to hear you're stuck with this annoying display glitch in Chrome DevTools on your Mac! I’ve seen this issue pop up before, and here are several tried-and-true fixes to get your mobile debugging view back to full screen:

• Reset DevTools to Default Layout
  Sometimes DevTools saves a corrupted layout state that causes this problem. To fix it:

  1. Open DevTools (Cmd + Opt + I or right-click → Inspect)
  2. Click the three-dot menu in the top-right corner of DevTools
  3. Go to Settings → Preferences
  4. Scroll down to the bottom and click Restore defaults and reload
     Wait for DevTools to restart, then check if the mobile view displays correctly.

• Verify Device Pixel Ratio (DPR) Settings
  An incorrectly set DPR can compress the view into a small corner. Here's how to check:

  1. In DevTools, toggle the mobile device view (Cmd + Shift + M)
  2. Make sure you’ve selected a standard device (like iPhone 14 or Pixel 7) from the device dropdown
  3. If you manually adjusted the DPR value (in the device settings panel), reset it to the default value for your selected device.

• Disable DevTools Extensions
  Third-party extensions for DevTools can sometimes interfere with its rendering:

  1. Open Chrome and go to chrome://extensions/
  2. Look for any extensions labeled "DevTools" or ones that interact with developer tools
  3. Toggle them off temporarily, then restart Chrome and re-open DevTools to test.

• Clear Chrome’s Cache and Site Data
  Stored cache or corrupted site settings might be causing the display issue:

  1. Go to Chrome’s menu → More Tools → Clear Browsing Data
  2. Select "Cached images and files" and "Site Settings"
  3. Choose a time range of "All time" and click Clear data
     Restart Chrome and try debugging again.

• Update Chrome to the Latest Version
  Your current Chrome version (65.0.3325.146) is quite outdated, and many DevTools bugs have been fixed in newer releases. If possible, go to Chrome’s menu → About Google Chrome to trigger an update, then restart the browser once it’s done.

Give these steps a shot in order—most users find that resetting DevTools or checking the DPR settings fixes this problem right away. Let me know if you need further help!
