for subsurfaces. Blending was disabled before rendering the subsurfaces<br />
and it is not checked whether the surfaces have an alpha channel or not.</p>
<p>This change addresses this problem by disabling blending after all<br />
subsurfaces have been rendered and enabling blending if a subsurface has<br />
an alpha channel.</p>
<p>Unfortunately this does not fix the investigated bug.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R108 KWin</div></div></div><br /><div><strong>BRANCH</strong><div><div>blending-for-subsurfaces</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D10060" rel="noreferrer">https://phabricator.kde.org/D10060</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>plugins/scenes/opengl/scene_opengl.cpp<br />
