Wrong rendering of images/components on STM32U5A9J-DK display (TouchGFX)

Hi,

I'm experimenting a bit with the TouchGFX designer and my STM32U5A9J-DK board. I created a simple project with couple of buttons and some labels and it worked straight out of the box. Imported on STM32CubeIDE, built and ran flawlessly. After playing a bit around I noticed that the display starting to show some artifacts. For example the following screen is rendered wrong, I cant really see why its even picking that red colour unless its some leftover from some previous images I used that was red.

Another example:

Depending on how I change the design, I may hit a clean/proper rendering.

At the beginning I thought it may be memory related but even increasing memory pool size for TouchGFX did not solve or improve it. 

Any hints? Thanks a lot!
