Comment 6 for bug 21596

This is cosmetic, but genuine. It may be that there is something we can do
about it. If someone could try the test below, that could help isolate the problem.

<mdz> seb128: the gdm slowness issue is something to do with how the background
is drawn; I see it here too
<mdz> seb128: did something change from bitmap to svg or something like that?
<ogra> mdz, nothing changed in the artwork
<seb128> mdz: not that I known of
<seb128> s/known/know/
<seb128> mdz: maybe gtk/cairo ...
<ogra> seb128, what does gdm use to draw the fullscreen background ? cairo, canvas ?
<seb128> mdz: cairo has created slowdown for some stuff
<mdz> seb128: I see this everywhere, on completely different hardware, so I
don't think it's X related
<mdz> it's completely cosmetic of course, but it gives the impression of
slowness :-/
<mdz> people will say that the entire system is slower because it makes them
feel this way
<ogra> its very likely that its cairo...
<seb128> it's the kind of issue not easy to track since it's subjective
<ogra> probably svg artwork would help
<mdz> it's basically scaling a bitmap and drawing it on the screen
<mdz> should
<mdz> be very quick
<mdz> seb128: are there any simpler programs which use cairo to do this, so that
we can more easily compare and profile them?
<seb128> one stuff to try for somebody noticing the difference with hoary would
be to run gdm with GTK 2.6 and 2.8
