Subject: [PATCH 009/131] Do not apply subpixel gamma-correction on XCB
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
To match rendering of subpixel antialiased text in Qt 4.8 and other
toolkits on X11, we should not apply gamma-correction. This also
makes the rendering of subpixel antialiased text closer to normal
antialiased text.
Task-number: QTBUG-41590
