Open 2009Windows7 opened this issue 3 months ago • 0 comments

When using the Aero11 Metro (8.1) theme with the registry value CaptionButtons set to 3, the caption buttons adopt the Win8 visual style, but their width is incorrect. They appear wider or narrower than expected.

Steps to Reproduce:

Apply the OpenGlass Aero11 Metro (8.1) theme.

Set the registry value:

HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM\CaptionButtons = 3

Open any window with caption buttons.

Observe that the width of the caption buttons does not match the expected Win8 style.

System Information:

Windows version: Windows 11 23H2

OpenGlass version: v2.4.3.2085

Theme: Aero11 Metro (8.1)

Registry modification: CaptionButtons=3

Screenshots / Logs:

Top: Windows 8.1 (expected width)

Bottom: Windows 11 23H2 with CaptionButtons=3 (incorrect width)

Additional Notes:

The height and visual style of the caption buttons match correctly; only the width is off.
