How do I know it's a alpha problem?

I have the same problem without xcompmgr with wmii before changeset:  2763.

I think that this is an xcompmgr bug. It seems to only happen with certain 
conifgurations (and nouveau is known to be troublesome). In my case, even 
enabling xcompmgr causes the problem, RGBA windows or no.

My best guess is that xcompmgr doesn't deal well with window managers drawing 
directly on their frame windows.

I said:
When I use wmii (earlier than 2763 ,so RGBA is enabled by default) without 
xcompmgr,the same problem occurred

P.S.
changeset 2763 says:
 Use RGBA windows only when required.
