Apple Mail layout cut off / hidden behind toolbar in Full Screen

Hi everyone,

Wanted to share a quick workaround for a frustrating visual bug I hit after a recent macOS update on my MacBook Air M4 (15.3-inch).

The Problem

When Apple Mail is in full-screen mode, the very first email at the top of the inbox pane is partially cut off and hidden underneath the top toolbar.

  • This only happens in full screen. It looks perfectly normal in a resized window.
  • Restarts, window resizing, and toggling the toolbar visibility (View → Hide/Show Toolbar) do not fix it.

The Solution

You can force Mail to instantly refresh and fix its layout grid with this simple tweak:

  1. Open Apple Mail.
  2. Go to the top menu and select View.
  3. Click Show Message Size to turn it on.

As soon as you enable this, the text instantly pops back down into alignment where it belongs! Hopefully, this saves you some troubleshooting time.
