when running this code (see image), 3 rows of pixels stop being redrawn normally and other oddities are observed (see image 2). Do not forget to start the CPU before starting the this program

Steps to reproduce:
start this code:

  use32
  org 0
  db 'MENUET01'
  dd 1
  dd START
  dd I_END
  dd MEM
  dd STACKTOP
  dd 0
  dd 0
START:
          mov eax, 70
          mov ebx, file_struct
          int 0x40
          test eax, eax
          jmp START
          mov eax,0xffffffff
          int 0x40
file_struct:
        dd 7
        dd 0
        dd message
        dd 0
        dd 0
        db '/sys/@notify',0
message: db '"swedcfvgbhnjmsx \n cfgvtbhnjsdfvgvtrcfebufbrh" -tdE',0
str_1: db '12345abcde-error0'
I_END:
  rb 4096
align 16
STACKTOP:
MEM:
