I compiled an application that works fine on the pc for android, and ran into a problem that the application starts flashing a lot while opening and closing new and previous scenes or functions, twitches horribly, and can even drive a person with epilepsy to a seizure.
As I understand it, the problem occurs exactly at function start/stage transition (Sorry, I am a newbie and my statements may be incorrect due to wrong wording).
Please tell me what could be the problem, or help me to solve it. I am attaching all the code of the program
