Description veldt 2010-11-14 08:35:40 UTC
Hi; when transmission-gtk "ghosts" my paused torrents, my CPU usage goes up (a lot), but only in murrine-based themes -- which use cairo. The heavy CPU occurs in a cairo routine (_cairo_bentley_ottmann_tessellate_polygon()). But only when text is displayed (paused/ghosted) with a non-1.0 alpha.

One or more of the following projects may be factors (all referenced in bug 655024): transmission-gtk, murrine, cairo, pango.

Report to cairo if problem persists.
