desktop wallpaper becomes visible while switching desktops. This was<br />
introduced in 2001 with SVN revision 90111<br />
(git <a href="https://phabricator.kde.org/R108:d194f74314285932eb72e1dfecd2816b63647e4e" style="background-color: #e7e7e7;

<p>In 2001 desktop switching was probably a costly action where it was not<br />
possible to just reorder the desktop in one frame. Nowadays we use<br />
mostly compositing and with compositing the ObscurringWindows are<br />
already disabled. But even in the case that no compositing is used I<br />
consider it as very unlikely that the desktop becomes visible during the<br />
switching. Given that I think it's time to remove this legacy solution.</p></div></div><br /><div><strong>TEST PLAN</strong><div><p>Compiles</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R108 KWin</div></div></div><br /><div><strong>BRANCH</strong><div><div>drop-obscuring-windows</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D7965" rel="noreferrer">https://phabricator.kde.org/D7965</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>workspace.cpp</div></div></div><br /><div><strong>To: </strong>graesslin, KWin, Plasma<br /><strong>Cc: </strong>plasma-devel, kwin, bwowk, ZrenBot, progwolff, lesliezhai, ali-mohamed, hardening, jensreuterberg, abetts, sebas, apol, mart<br /></div>
