Hi! I see your Flightview app calendar is showing a pitch black screen, making it impossible to see dates. That definitely sounds inconvenient. To help you best, could you please tell me if this issue is happening right after you open the app or only when trying to access the calendar? Also, have you recently updated the app or changed any settings like dark mode or accessibility options on your device?

Meanwhile, here are some initial steps we can try on your Windows device using WebKit:

1. Refresh the app or page: Sometimes a quick reload can fix display glitches. You can try closing the Flightview calendar tab or app and reopening it.

2. Check display settings: Flightview respects your system settings for accessibility such as text/font size or dark mode. On Windows 10, go to Settings > Personalization > Colors to see if your color scheme might be affecting visibility. Switching between light and dark might reveal if this is related.

3. Clear browser cache (if using Flightview web version): In your WebKit browser settings, clear cached images and files. Cached data occasionally causes display issues.

4. Update the app or browser: Ensure Flightview app (if using one) and your WebKit browser are updated to the latest versions.

5. Disable any browser extensions: Some extensions or ad blockers can interfere with content rendering.

If these don’t help, we can try more advanced tweaks like adjusting graphics acceleration settings or reinstalling the app. Please let me know what you've tried so far, and I’ll guide you further!

Are you currently accessing Flightview via the app or a web browser? That will help me tailor the next steps.
