Hi Paul,
When I opened my 9.10 project in 9.20, all of my variant images lost their file name, and all images defaulted to Alpha8.
When I ran, all images were greyscale as expected.
I switched to Native (Platform package STM.STM32.RGB888) and the GUI crashes at "Create Embedded Wizard Root Object... " without any error code.
If I switch to RGB565 everything is fine except for losing transparency (rounded corners etc) as expected.
The previous issue was a renamed define for the QSPI.
