Hello, when you edit the Google Sheets CloudShow app settings there is a 'Mode' option. Have you tried each of the 4 modes to see if one of them gives you the desired look? Thanks!

The issue is unfortunately the way Google Sheets renders its content, there's nothing we can do to work around this, sorry.

That's unfortunate, it sounds like there might be an issue with the way Chromium interacts with fonts in Windows 7. If Windows 10 solves the issue I would strongly recommend updating to Windows 10, it's unlikely we'll be able to solve that on our end.
