Ok, I found the plugin which causes this problem. I does not make any sense to me, but this problem occurs only when the image loading plugin for PNG is enabled.
I reinstalled everything, from fgrlx over xgl to compiz... and the problem was gone. After that, I played around with the options, enabled and configured some things. After a restart, the resize-problem was back again.. after disabling all the plugins one for one, i found out that the PNG-Plugin causes this issues.
I hope this information helps to solve this problem.
