Bitcoin 0.5 rc3: black popup window when hover recent transactions #613

See the screenshot uploaded here: http://imageshack.us/photo/my-images/155/capturadetelagw.png/

Tested on:

Os: Debian Wheezy 64 Bitcoin: 0.5 rc3

Confirmed -- I've also seen this, it happens on Linux in some cases but not other OSes (afaik).

The black box is a tooltip that somehow doesn't render succesfully.

Might be Qt related or some problem in the rendering in overviewpage.cpp

I usually get the black rectangle when i hover over that area, but today I noticed that if I hover over the 'unconfirmed' number to the left and then quickly move to the right, I get a pattern of random-looking coloured dots, rather than solid black. I can almost make out what the tooltip says through the dots. So this isn't just a CSS issue setting foreground and background to the same colour; it's seems to be a memory corruption issue, which is significantly worse.

I would include screenshots, but someone would find a way of decoding the 'random' dots to read my private keys. :)

Confirmed on Gentoo.

#653 fixes this issue
