gdk_pixbuf_get_from_source: only reuse surfaces with matching format (1.02 KB, patch)

Description Sindhu S 2013-09-04 08:53:41 UTC 
I have epiphany built from git master today. There is an odd cursor appearing when mouse pointer is on an image that is opened inside epiphany. If I take a screenshot, in the screenshot the normal mouse pointer appears.

Actually a WK bug. I can reproduce this in MiniBrowser and GtkLauncher.

So this seems to be a bug in GTK+. The following commit is the first where this happens:

    gdk_pixbuf_get_from_surface: Avoid copying if source is image surface
    
    If the source surface is an image surface we don't need to coerce
    it to one.

I might be stupidly wrong but my bet is that convert_alpha() cannot deal with CAIRO_FORMAT_A1 ?

Otherwise the convertion functions will return rubbish.
