E.g.

x11perf -getimage{10,100,500}

Also, someone on IRC pointed out that due to limitations in the Qt X11 backend,
starting plasma (and maybe Qt apps in general) with --graphicssystem=raster may
work better. (You can also try --graphicssystem=opengl, but the Mesa driver
most likely isn't quite up to that yet)
