Since the <tt style="background: #ebebeb; font-size: 13px;">Image</tt> has its <tt style="background: #ebebeb; font-size: 13px;">opacity</tt> transition to zero, you can see through it to the background <tt style="background: #ebebeb; font-size: 13px;">Rectangle</tt> behind it.<br />
Using <tt style="background: #ebebeb; font-size: 13px;">layer</tt> during the transition we can combine the entire item into a single surface and animate its <tt style="background: #ebebeb; font-size: 13px;">opacity</tt> as a whole.</p>
<p>BUG: 410313<br />
FIXED-IN: 5.17.0</p></div></div><br /><div><strong>TEST PLAN</strong><div><ul class="remarkup-list">
<li class="remarkup-list-item">Wallpaper transition doesn't flash anymore. Previously was most noticeable when just changing the size mode (e.g. from stretched to centered)</li>
</ul>
<p>Not really sure about the performance implications of using <tt style="background: #ebebeb; font-size: 13px;">layer</tt> on such a a large surface?</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R120 Plasma Workspace</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D23021">https://phabricator.kde.org/D23021</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>wallpapers/image/imagepackage/contents/ui/main.qml</div></div></div><br /><div><strong>To: </strong>broulik, Plasma<br /><strong>Cc: </strong>plasma-devel, LeGast00n, jraleigh, fbampaloukas, GB_2, ragreen, Pitel, ZrenBot, himcesjf, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas, apol, mart<br /></div>
