The smilies at the right side of the "edit box" when posting a new post or replying are acting weird:
A small area box in the colour of the background appears and gets larger till the icon is gone. Then the icon comes back and the same thing starts all over.
Some icons like the first 4 of the first line are shown all the time while others are almost always "gone", appear and reappear.
See the screenshot for what it looks like.

Is it an error of the NVidia driver? Or what can cause such error?
Running V08 with nVidia-x86-256.53-remix-v08-PAE.sq4.lzm gives me no such error. The 1.0 beta driver is the Vidia-260.19.36-porteus-v1.0_beta-x86_64.xzm one.
Update
See last post by fanthom for the solution.
