Subject: fix: activate background material on windows
|
|
|
|
This patch adds a condition to the HWND message handler to allow windows
|
|
with translucent background materials to become activated.
|
|
|
|
It also ensures the lParam of WM_NCACTIVATE is set to -1 so as to not repaint
|
|
the client area, which can lead to a title bar incorrectly being displayed in
|
|
frameless windows.
|
|
|
|
This patch likely can't be upstreamed as-is, as Chromium doesn't have
|
|
this use case in mind currently.
