I have a really annoying problem with the processing editor.
If open menu the buttons are black. If I roll over with the mouse they appear. After some typing and using the menu the whole editor starts to show artifacts and the display driver crashes.
The driver of the Radeon HD6970M is up to date (8.850.6.0 / 11.5a RC3 hotfix) and I'm using processing 1.5.1.
Processing 1.2.1 produces the same error.
Windows 7 has all updates installed.
I uploaded a movie clip taken with my mobile phone to demonstrate the problem (sorry for the bad quality)
