Hello @Tucu ,

Could you please provide more information on what board or MCU you are using for your development? 
What version of TouchGFX are you using? 

Is the flickering happening once or does it continue when it starts?

Could you please try a similar implementation to the Modal Window example in the TouchGFX designer to test if the flickering happens?
