<div style="margin: 8px 0; padding: 0 12px;"><p style="padding: 0; margin: 8px;">I'm 95% sure you need to rotate your softwareCursorHotspot.</p>
<p style="padding: 0; margin: 8px;">It's something hard to see, becuase you'll only be off by a few px.</p>
<p style="padding: 0; margin: 8px;">The only reason I'm not scaling the offset is because we're not scaling the contents of the cursor planet (which is arguably wrong), you are rotating it.</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/D8627" rel="noreferrer">https://phabricator.kde.org/D8627</a></div></div><br /><div><strong>To: </strong>graesslin, KWin, Plasma<br /><strong>Cc: </strong>davidedmundson, plasma-devel, kwin, bwowk, ZrenBot, progwolff, lesliezhai, ali-mohamed, hardening, jensreuterberg, abetts, sebas, apol, mart<br /></div>
