Hi there! I understand your Cryptogram game display is shrinking while you play. Let's get this sorted out. To start, could you tell me a bit more about the issue?

- Does the entire game window shrink, or just the text and puzzle area?
- Does this happen gradually during gameplay or suddenly at some point?
- Have you noticed if it occurs after a certain action or update?
- Also, are you running the game in fullscreen or windowed mode?

Knowing these details will help me guide you better. Meanwhile, here are some initial steps you can try on your Windows 10 WebKit setup:

1. Check Display Scaling Settings:
- Right-click on your desktop and select "Display settings."
- Look for "Scale and layout" and ensure it's set to 100% or a recommended value.
- Sometimes high scaling values can cause apps to appear smaller or behave oddly.

2. Adjust In-Game Settings:
- Open the Cryptogram game settings.
- Look for any options related to font size, zoom, or display scaling and adjust them.

3. Update Graphics Drivers:
- Ensure your graphics drivers are up to date, as outdated drivers may cause display glitches.

4. Reinstall the Game:
- If the issue started recently, uninstalling and reinstalling the app can reset settings that might have been corrupted.

If you've already tried any of these, let me know which ones, and we can dig deeper or explore other causes. Also, sometimes app updates or Windows updates can cause scaling issues, so that info could help.

Are you able to check these and share what you find? I'll be here to help!
