TouchGFX display glitch after power off-on, but not after flash build.

[MM..1]

I test app on U599. GUI task priority set little low as hw task. After flash all works ok, but after powering start gui glitch on SVG fade animation or other redraw.

After swap priority GUI up all works ok. Why this after flash difference occurs?

Hello @MM..1 ,

 

If it is on the STM32U599-DK, could you share the project so we can test it?

No DK, custom board and LCD.

Hello @MM..1 ,

 

I was expecting that :\

Did you test performances?
When you redraw your SVG, what is the performance (after build and after reset)?

I don't understand this: "After swap priority GUI up all works ok"
You have changed the priorities and now it works? After build and after reset?
