I make a bitmap conversion from 32x32 png format arrow icon (attached)

Saving the bitmap with "True color with alpha channel" produce this structure
GUI_CONST_STORAGE GUI_BITMAP bmarrowD = {
32, // xSize
32, // ySize
128, // BytesPerLine
32, // BitsPerPixel
(unsigned char *)_acarrowD, // Pointer to picture data
NULL, // Pointer to palette
GUI_DRAW_BMP8888
};
and is correctly displayed by GUI_DrawBitmap

But if I change the saving options and I use "True color with alpha channel, compressed"
The new strcuture is

GUI_CONST_STORAGE GUI_BITMAP bmarrowD = {
32, // xSize
32, // ySize
128, // BytesPerLine
32, // BitsPerPixel
(unsigned char *)_acarrowD, // Pointer to picture data
NULL, // Pointer to palette
GUI_DRAW_RLE32
};

but GUI_DrawBitmap can't display the arrow image

I have other compressed bitmaps but saved by GUI_DRAW_RLEM16 option and they are displayed correctly

Thanks Adrian
I am sorry for reply delay
I don't have the 5.28
I am not sure but I think the problem is related to the low memory in my device
My memory config is
#define GUI_NUMBYTES 0x4000
