Incorrect results drawing horizontal and vertical lines to the LFB returned by VBE

I finally managed to draw a cyan pixel on the screen using the VESA BIOS Extensions (1920px * 1080px, 24bpp).

;esi = bytes per scan line;edx = physical address of linear framebuffer memory.;ebx = x coord * 3;ecx = y coordDrawPixel:    push edx    mov edx, 0    mov eax, 0    lea eax, [esi]    ;mov ecx, 0    mul ecx    add eax, ebx    jmp drawdraw:    pop edx    add edx, eax    mov ebx, 0x3296fa    mov [edx], ebx    ret

I tried to draw a cyan horizontal line on the screen using a "for loop" this way:

mov edi, 1920call drawLoopjmp $drawLoop:    dec edi                                       ;decrease edi    cmp edi, 0                                    ;is edi equal to zero?    jl doneLoop                                   ;then return    imul ebx, edi, 3                              ;multiply edi by three and save the result in ebx    mov ecx, 0                                    ;y = 0    mov esi, ModeInfoBlock + 10h    mov edx, dword[ModeInfoBlock + 28h]    call DrawPixel                                ;Draw it!    jmp drawLoop                                  ;run this againdoneLoop:    ret

However, this doesn't work: it draws a green line instead.

When I try to draw a vertical line again with the draw/draw pixel code, it doesn't work either. It plots pixels with random colors everywhere. Here's how I use the DrawPixel function to draw a vertical line:

%include "../kernel/Services/Display/display.asm"kernel:    mov edi, 1080    call drawLoop    jmp $drawLoop:    dec edi    cmp edi, 0    jl doneLoop    mov ecx, edi    mov ebx, 0    mov esi, ModeInfoBlock + 10h    mov edx, dword[ModeInfoBlock + 28h]    call DrawPixel    jmp drawLoopdoneLoop:    ret

Any way to solve these problems?
