Review forms with the opacity not set to 100%.

Remarks

A form's Opacity property determines the transparency level of the form. Forms with the Opacity property not set to 100% will be partially or completely transparent. Review these forms to ensure that this is the desired behavior.

Resolution

Review forms with the Opacity value not set to 100% and determine whether they should be partially transparent. If they should not, change the Opacity property in the Windows Form Designer Properties window.
