Faulty Understanding Application Structure 1.1.0 example, which shows the Model-View-Presenter (MVP) design pattern: crashes on target

[DPant.1]

Using TouchGfx 4.14.0, select "Understanding Application Structure" example and run on target (stm32f469i-disco).

It will stack overflow on the 3rd transition:

The cure is to increase stack size from 2048 to 3072 (\TouchGFXProjects\MyApplication_1\Core\Src\main.c, line 69).

Please fix!

Hi,

Thank you for finding this issue. We will fix this. Has a similar issue occurred for other UI templates you have tried?

With stm32f469i-disco and TouchGfx 4.14.0:

• many of the examples don't scale to full screen size (800x480) so result looks odd...

FlexButtonExample\1.1.0\

TextExample\1.1.0\

TextRotateExample\1.1.0\

ModalWindowExample\1.1.0\

LineAndCircleExample\1.1.0\

• others gives just a black screen (stack increase didn't help, so something else must be there but didn't have time to dig deeper):

PixelDataExample\1.2.0\

ListLayout\1.1.0\

TextureMapperExample\2.0.0\

ClockExample\2.0.0\

• not building succesfully

TouchGFXDemo2\1.3.0\

Hope you can double check them and find fixes.

PS: the "black screen" examples work if imported and rebuilt from STM32CubeIDE (Generate Code -> Browse Code -> --\STM32CubeIDE\.project -> Run).

Noticed that resulted STM32CubeIDE\Debug\STM32F469I-DISCO.hex is smaller than the original not-working TouchGFX\build\bin\target.hex and this can be seen in the map too:
