<p>However I still see a significant performance regression though. Switching tabs in Kate is now quite slow, especially when there are many open and you use a keyboard shortcut to do so. I see the spinning busy cursor all the time. The Tools area also changes its vertical height a bit when changing tabs, which is odd.</p>

<p>Any performance regressions when a kate widget is involved (Kate, KDevelop) is likely to due to the fact that tab switching results in a spam of repainting because of incessant toggling of a toolbar's visible property, which results in costly repainting for no reason. I've already optimized what I can from the QStyle side, and anything further will have to be fixed in the offending widget.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R31 Breeze</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D27669">https://phabricator.kde.org/D27669</a></div></div><br /><div><strong>To: </strong>cblack, Plasma, Breeze, VDG, hpereiradacosta, davidre<br /><strong>Cc: </strong>abstractdevelop, IlyaBizyaev, davidre, davidedmundson, hpereiradacosta, ngraham, manueljlin, niccolove, ndavis, plasma-devel, Orage, LeGast00n, The-Feren-OS-Dev, cblack, jraleigh, zachus, fbampaloukas, GB_2, ragreen, ZrenBot, himcesjf, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas, apol, ahiemstra, mart<br /></div>
