My experience is similar, but not identical: For me, OpenGL results in delays
as the system paints images. It looks like OpenGL is trying to create smooth
"fade" transitions rather than the abrupt "cuts" that Qt produces. These
delays are most noticeable when switching screens. I don't recall big delays
when just moving from item to item in a screen -- but I might have missed
that, since I only played with the OpenGL renderer briefly, since I prefer
quick transitions to smooth fades in menus, anyhow.
