FrameBuffer being populated incorrectly?

[Hafez1]

Hi. Using a STM32L4R9I-Discovery board with a connected ST7789VI screen. I'm trying to display a design I made in TouchGFX, yet I'm getting some distortion in the middle and quite a bit of misalignment where the bottom part of the screen is on the top and the top is on the bottom. ALso, I've noticed that the right and left sides of the screen sometimes get mixed up. 

I initially thought it was the flushing that was the issue, but I printed the framebuffer content pre-flushing and I noticed that I had corrupt/missing pixel data around where I'm experiencing the distortion (pictures attached). Can anyone help out please?

Ignore the attached files. Just the link. Thanks Mohammad.

Thank you!

I can see in your X-CUBE-TOUCHGFX configuration, you have set the display to be 320x240, but as we discussed it should be 240x320

Display dimensions

So, please change the Width to 240 and the Height to 320, and check if it helps.
