A short demonstration of GNOME Software scrolling extremely slowly when the mouse hovers the grid of applications in the catalogue browser, and not lagging at all when the mouse is in the margin on the side of that view.

   Finally, an explanation for #GNOMESoftware's slow scrolling when browsing apps! Thanks to @kdwk for finding out that it only happens when the mouse is over the items instead of "in the margin on the side"…

   The fact that it is hundreds of times slower, however, was a rather unexpected finding :blobsweats:

   I added some #Sysprof performance profiles to this ticket: https://gitlab.gnome.org/GNOME/gnome-software/-/issues/2172

   I wonder whether it's #GTK, the pixbufs, or something else in the #GNOME graphics stack 🤔
