<p style="padding: 0; margin: 8px;">Always using GL_LINEAR AFAIK is fine, but always generating mipmaps has a cost.</p>

<p style="padding: 0; margin: 8px;">if (windowPixmap->surface()->scale() != output->scale())</p>

<p style="padding: 0; margin: 8px;">We also probably only want to generate mipmaps if the contents have changed.</p>

<p style="padding: 0; margin: 8px;">GLTexture has a dirty() flag which signifes this.</p></div></div></div></div></div><br /><div><strong>REPOSITORY</strong><div><div>R108 KWin</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D23669">https://phabricator.kde.org/D23669</a></div></div><br /><div><strong>To: </strong>romangg, KWin<br /><strong>Cc: </strong>davidedmundson, kwin, LeGast00n, The-Feren-OS-Dev, sbergeron, jraleigh, fbampaloukas, GB_2, mkulinski, ragreen, jackyalcine, Pitel, iodelay, crozbo, bwowk, ZrenBot, ngraham, alexeymin, himcesjf, lesliezhai, ali-mohamed, hardening, romangg, jensreuterberg, abetts, sebas, apol, mart<br /></div>
