STemwin background color of a text

Ala

Hi there

I'm currently working on a simple project and it is a simple 7inch LCD using a STM32H743IIT6 board.

I used GUIDRV_LIN for display driver. and I have set all the LTDC and FMC, etc.

here are my issues:

1- first: in a simple window I have some TEXT as my widgets

the problem is in the init part where we set for example Font, Alignment, etc. I set a color for TEXT background as below

hItem = WM_GetDialogItem(pMsg->hWin, ID_TEXT_20);
TEXT_SetTextAlign(hItem, GUI_TA_HCENTER | GUI_TA_VCENTER);
TEXT_SetFont(hItem, &GUI_Font24B_ASCII);
TEXT_SetText(hItem, "DG1");
TEXT_SetBkColor(hItem, GUI_LIGHTBLUE);

but the thing is that I can not see the background color when I load the code to my board!

everything is just fine, except this issue. any Ideas?

2-there are some white dots here and there sometimes when I power on the board! I have the config multiple time, all seems right(as you all know, LTDC and FMC etc. are too long to put and describe here, that's why I didn't bring them up here)

so what is this one all about? any Idea?

thanks a lot in advance
