1449271 - Add a pref to force an opaque GL context to be used for the window

Status: RESOLVED FIXED

(Core :: Widget: Cocoa, enhancement)

Description

[Markus Stange [:mstange]]

We're aware that having a transparent OpenGL context hurts performance and battery life. For testing purposes, it would be nice to have a pref to force the context to be opaque.

Unfortunately, setting this pref will break the rounded window corners and any vibrancy effects (e.g. in the tab bar and the side bar).
