Weird graphic/performance issues on anki

[emperor]

I've been using 11.10 for a while now and since it has not been fixed so far I thought I'd report it. I have tested on 2 computers, same result for both.
When starting anki, it shows up really weird, with no top bar whatsoever (without metacity crashing here). My whole computer is becoming really slow - the other computer tested which is slower become almost totally unresponsive. My computer also became unresponsive when starting it when I didn't have fglrx installed, no idea if it is related though.

Outputs are attached - one of the outputs is
QWidget::setMinimumSize: (MainWindow/AnkiQt) The largest allowed size is (16777215,16777215)
which I initially thought was the problem.
But then I downloaded the anki sourcecode and commented out all occurances of setMinimium Size - then the error did not show up on the console anymore but I did not work either.

So no idea how to fix it myself and not sure if it's a bug in anki or in some other package. (And if anybody experiences something similar: my 'workaround' is to use anki for windows with wine).

Anyways, thanks a lot.

Attached:

(both in 1 tar since I didn't see a possibility to attach multiple files)

Just to note: There are X errors in the output that probably should not occur from a mere use of pyQt (which anki is based on)
