I recently encountered a formatting issue when I open a form. In the screenshot below, the formatting looks unattractive and the size of the objects are smaller in length. When I download the template and open it in InfoPath, I get the same ugly format.
I was able to identify another possible cause: screen resolution
- Right click on your desktop and click Display Settings
- Adjust option "Change the size of text, apps and other items" to 100%
- Sign out of your account in Windows
After logging in, open your form. You will see the correct format
Take note that this solution is applicable with Windows 10 with a 3200 x 1800 recommended resolution.
