1932521 - Firefox nightly is not interacting with DWM in windows properly

Status: RESOLVED DUPLICATE of bug 1931747

(Core :: Widget: Win32, defect)

Description

[Liam Lawson]

Attachment: A showcase of how nightly currently looks in windows 11, see that sharp edges? that is not meant to be happening.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:134.0) Gecko/20100101 Firefox/134.0

Steps to reproduce:

It should be somewhat self explanatory.

1. Open firefox nightly
2. minimise it if it is maximised
3. notice how odd it looks compared to stable.

Actual results:

the window should have rounded edges like most other applications in windows 11

Expected results:

the edges are sharp.

correction: the window SHOULD have rounded edges. this is the expected behaviour.
the current nightly build does NOT.
