STM32 LTDC TouchGFX GUI Glitching

[Trampler]

What could be the cause of this glitch on my LCD-TFT screen? My system includes an F429 MCU, an SDRAM, and a 24-bit LCD panel. The interface was designed with TouchGFX, and the circuit board was designed by me.

Try add some real gui elements. Here you have no info relevant. Debug faults...

Or for example use two screens and setup delay and transition screen 1 to 2 and back....
