Hi there! I see you’re experiencing a graphic error with the Zoom Earth app on your Mac running OS X 10.15. Could you please share a bit more about the issue? For example, are you seeing distorted maps, blank screens, or problems when zooming in/out? Any details you provide will help me suggest the best fix.

In the meantime, here are some common steps that often resolve graphic errors in Zoom Earth:

1. Restart the Zoom Earth app: Sometimes a simple restart can clear temporary glitches.

2. Clear browser cache (if you are using Zoom Earth via a browser):
- Open your browser’s settings.
- Find the option to clear cache and cookies.
- Restart the browser and try again.

3. Disable any browser extensions that might interfere with graphics rendering, especially ad blockers or script blockers.

4. Check for updates: Make sure your Zoom Earth app or browser is up to date, as updates often fix bugs.

5. Try a different browser if you’re accessing Zoom Earth via browser (Safari, Chrome, Firefox).

6. Check your Mac’s graphic settings:
- Go to Apple menu > System Preferences > Displays, and make sure your resolution settings are normal.
- Also, ensure your Mac’s GPU drivers are up to date (this normally updates with macOS updates for OS X 10.15).

If the issue happens specifically when zooming or redrawing the map, it could be related to how the app handles graphic layers, as some users have seen redraw problems after zoom events in similar apps.

Could you please confirm if you are using a standalone Zoom Earth app or accessing it through a browser? Also, did the error start after a recent update or is it ongoing? This info will help me narrow down the next steps for you.
