STM32F7 LTDC and TIM2

If I configure the LTDC interface on my STM32F746IE device, TIM2 is disabled.

I can reset the state of LTDC_R2 (PA1), then TIM2 is available, but disables itself after reconfiguring LTDC.

PA0 = TIM2 CH1

PA2 = TIM2 CH3

I searched accros the datasheet, reference manual and errata but was not able to find any restriction by using TIM2 and LTDC simultaneously.

Do I miss something here or is this a bug?
