Test "GtkDrawingArea - Circles" is still slow as without your patch (takes
about 40 s). Another problem is a desynchronization of X client and X server:
while gtkperf was already running the next test (GtkDrawingArea - Text) the X
server still was drawing circles (for about 2 s).

But GtkDrawingArea - Lines - time:  5,01.
