Comment 16 for bug 759803

I'm using Kubuntu 11.04 and am getting some really similar glitches with normal (effects-enabled) KDE (not 100% reproducably, though). 24bpp is a really common value for all the machines I used in the last 8 years (X has been auto-detecting this for years). This is physical machines I'm talking about, btw.
IIRC, it used to be a pretty standard reply that 24bpp and 32bpp were essentially the same thing and, for some reason I never quite understood, X11 prefers the former.

I believe it is quite safe to say that 24bpp need to be supported properly...
