recently Firefox has started leaving a small gap at the top of the window with the desktop background (the light blue in the screenshot) is visible when the window is maximized.

This issue doesn't occur with any other program and occurs in troubleshoot mode.

Hi there,

Thank you for reaching out! This issue is tracked under bug 1993474, and the fix should land soon. I'll keep you updated.

To clarify, do you use several monitors?

Yes I do it only occurs on one of them. Although today it hasn't occurred so that fix might have been deployed

Hi there,

A quick update. The fix for bug 1993474 targets Firefox 147, and this version will be released on January 13.
