Description antti.niemi 2013-04-11 18:12:39 UTC
LibreOffice Calc gets unresponsive and causes excessive CPU load when opening and/or trying to scroll an XLS spreadsheet file with three charts and a few thousand data points. Increasing memory limits in Tools->Options->Libreoffice->Memory doesn't have much effect. Disabling graphics antialiasing helps a lot but scrolling is still somewhat sluggish.

Adding Need_Advice - relatively sure this is a dupe of bug 47726 just affecting a different component. Seems no good to say the least
