Let me talk about the latter issue on shell command output first. I'll talk about the former issue on scrolling shortly after that. I'm afraid it's not much relevant to scrolling. Roughly speaking, when the GTK+2 GUI sends a series of drawing requests to the X server, it completely leaves to the server what eventually appears on the screen. In other words, it doesn't care much about whether or not each frame is drawn on the screen. Not a few frames could be skipped undrawn. In contrast, the GTK+3 GUI draws a complete picture on a off-screen first and then dump it at the server in accordance with a frame clock, so that every frame will surely be drawn on the screen. Ensuring each frame is drawn is important to realize animation of high quality and considered to be one of inevitable features of modern GUI. For those reasons, I'm now inclined to think that the performance test you're referring to doesn't make much sense for the purpose of comparison, because any GUI that cuts corners always beats a deadly earnest one at time race. :) As for scrolling, I suspect the refresh rate of the display you're using, because GTK+ 3 uses a frame clock to update as noted above. <snip> > I hope this gives enough information to help identify the issue.
