[STM32F7] Overrun error with USART6

I am using a STM32F746NG discovery board. My project is supposed to receive, display and store data. It receives data over USART6 in asynchronous mode using DMA. To display the data I want to use the STemWin library. 

When I compile my project with the STemWin library the USART DMA interrupts are not executed anymore.

I have no clue what the problem might be and how to debug it. Can anyone give me some advice?
