System Workbench for STM32

Hi,

I have built a very simple GFX screen using the ToughGFX designer for my 412-disco board, works perfect in the simulator, but does this when downloaded. I have tried two 412 disco boards both have same issue..

I've downloaded directly from Designer, and also from STM_IDE, but always met with the same fuzzy screen.. the screen is OK, as i've run the simple HELLO World TEM which is in 1.27 framework, all work ok

Any pointers would be gratefully received, areas to look...

Andy
