1296753 - Incorrect title bar colour for minimised windows in Windows 10

Status: UNCONFIRMED

(Core :: Widget: Win32, defect, P3)

Description

[Daniel Beardsmore]

Attachment: Inactive window wrong title bar colour.png

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:47.0) Gecko/20100101 Firefox/47.0
Build ID: 20160623154057

Steps to reproduce:

Windows 10, with "Show color on Start, taskbar, action center, and title bar" enabled.

Minimise a window, then hover over its taskbar thumbnail. Windows will show a snapshot of the window.


Actual results:

The caption text of the window is shown in the correct foreground and background colours. The remainder of the title bar draws in white, being either a complete failure to draw colour, or an incorrect assumption that the title bar should be pure white (Windows 10 default).

Generally, only minimised windows are affected, but certain windows opened by JavaScript (e.g. all links to images on the deskthority.net forum) will draw a 100% white title bar with black text and and widgets, indicating another code path where Firefox forgets about the Windows 10 update to support accents.

Considering the implications of bug 1196266 (albeit one which I can't reproduce) and the misaligned title bar widgets (possibly fixed in 48: I have 47 on this PC but 48 at work) I echo the sentiments about simply letting the OS draw the title bar.


Expected results:

Native title bars that just draw correctly at all times.

polishy, but also kind of ugly.
