Hello,
I am a beginner with TouchGFX. I created two screens with a slide transition and found some questions would like to confirm.
1) Text broken
I found that when the B screen transitions to the A screen, the Big Text contains text broken during transition and is recoverable.
CPU frequency = 280MHz (recoverable) (00:00:07, with 0.25 speed)

Contains Black pixels
CPU frequency = 160MHz (irrecoverable)

Text pixels always missing after transition
- How the CPU frequency influence this issue?
- Could it be fixed if using double buffer for TouchGFX?

2) Animation Storage
According to the instructions, I should set a full-screen size buffer for the animation storage. However, I set the half-buffer since out of RAM resources.

- I would like to confirm that this issue would be fixed when the animation buffer is full-screen size?
