So I assume this is one out of many variants of meta <a class="bz_bug_link bz_status_NEW " title="NEW - [META] Bug related to Main Loop refactoring" href="show_bug.cgi?id=119334">bug 119334</a>. B. The general performance issues on MacOS make things even worse (especially Retina screens). See for example <a class="bz_bug_link bz_status_NEW " title="NEW - MacOS: CPU utilization while scrolling through a plain text document is around 90% on Retina HiDPI screens" href="show_bug.cgi?id=113104">bug 113104</a> or <a class="bz_bug_link bz_status_NEW " title="NEW - macOS: high CPU when scrolling around" href="show_bug.cgi?id=103864">bug 103864</a></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
