[PyQt] Possible bug in handling '-visual TrueColor' option

[Benno Dielmann]

I think it's an X11 problem. Take a look at the comments to this blog entry:

http://zrusin.blogspot.com/2006/10/argb-windows.html

Other people have the same issues with the c++ version.

By the way, I tried the argb.py you attached in one of your previous mails and 
I don't get these errors.

Benno.
