[CLOSED] Maps in Editor are getting blurried after I save

After I've created a map, I expect it to be as I left it when I saved it.

Instead, when I come back to continue my work, the areas around the countries that I've created gets all blurred and it becomes impossible to creat any more countries in those areas since I can't distinguish the shores and the rivers.

Information:
Browser: Google Chrome
Browser version: 87.0.4280.88

Can you provide some more information? Which map has the issue? Can you post screenshots?

Closing this since I can't reproduce the issue and the OP did not reply with any further info.
