--- Comment #4 from Joel Feiner <[email protected]> 2009-08-02 09:20:41 PST --- (In reply to comment #1) > If Firefox (or any other app, for that matter) uses XGetImage for scrolling, > it's broken and needs to be fixed. > I've heard that Firefox uses XGetImage when rendering "native" widgets, i.e., that it renders the widgets using the native GTK+ libraries and then uses XGetImage to grab the rendered widget and then uses that image to actually draw the widgets. That's why I thought there might be some relationship between scrolling (pages have widgets) and XGetImage. > The problem could indeed be due to software fallbacks though.

Please stick > to a single operation as much as possible during any profile run. > I attached two oprofile reports and unlike last time I tried to file a bug report, they actually look valid. Note that I rebuilt my X stack from Git this morning (latest master) and the kernel code is also up to date, using this Git URL: http://www.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git (if you need a reference point). The reports include line numbers so I thought that information might be useful. > You could also try enabling the fallback debugging code in xserver/exa or the > driver and see if antything sticks out.
