Hi, I did some profiling of Firefox's html5 video element which uses cairo, and the low performance I observed seems to be caused by not using XShmPutImage for uploading video-data. Instead, XPutImage is used - with xcb's 16kb buffer this results in about ~25k cs/s, slowing my machine down to a crawl. Does cairo support using the XSHM extensions, or are there patches available? Thanks you in advance, Clemens -- cairo mailing list [email protected] http://lists.cairographics.org/mailman/listinfo/cairo
