<p>The mipmap filter is the default linear filter, which results in soft images. Using a filter with a sharpening kernel, such as a cubic or a windowed sinc filter would produce better results, but this is still an improvement over not using a mipmap filter at all.</p>
<p>The scaling is gamma-correct when desktop GL is used.</p>
<p>Note that this patch only modifies the GLX path.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R242 Plasma Framework (Library)</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D10251" rel="noreferrer">https://phabricator.kde.org/D10251</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>src/declarativeimports/core/windowthumbnail.cpp<br />
