And it's "fixed".
When people see me using root in pastebins for console output they always
say "you really should not use root, make a user" or something along those
lines. (I fully agree to that BTW)

Well, I did for the Qt stuff. As a user I get the issues mentioned in the
first post.

As root I actually have everything working just fine. Qt QML examples work
perfectly. I actually wasn't expecting an example like samegame to be
buttery smooth, but it is! Pros to the Qt team!

So it seems to be some issue with permissions. And that is certainly not
clear when looking at the output I saw (in the first post).

On big fat note though. Do not use startx with twm. Qt examples and windows
then open in some bugged transparent way. Use a "slightly" more modern
window manager like openbox.

Now I just have to figure out which permissions are missing for the user.
