Rendering multiple text objects--especially cells in a Calc sheet when scrolling or resizing [1][2]--has slowed with default HA or CPU only rendering, though still reasonable with OpenGL. Likely requires additional font caching of some kind. =-ref-= {1][2] <a class="bz_bug_link bz_status_NEW " title="NEW - Calc 5.3.2.2 impossibly slow on scrolling and altering column widths" href="show_bug.cgi?id=107770">bug 107770</a> and <a class="bz_bug_link bz_status_NEW " title="NEW - App. one second delay when using Page UP/DOWN and switching between tabs" href="show_bug.cgi?id=109220">bug 109220</a></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
