Line - incorrect line coloring when the control style is enabled "simple"

[EpicNet]

I am using "mIRC v7.67" + "DCX dll v3.1-git469" in system "Windows 8.1 x64".

When using the style simple, a colored line is drawn, and a duplicate in the form of a light gray line is drawn next to it. At the same time, as can see in the screenshot, the first cross of the two lines has no color at all.

It seems that something is not working correctly here. Would like to see a fix for this problem. Thanks.

Script to reproduce the problem. To run, press F5 or enter the command /line_test:

alias F5 { line_test }
alias -l line_test {
  if ($dialog(line_test)) .dialog -x line_test | else { .dialog -m line_test line_test }
}
dialog -l line_test {
  title "Line test"
  icon $mircexe,0
  option pixels
  size -1 -1 370 120
}
on *:DIALOG:line_test:init:0:{
  .dcx Mark $dname line_test_work
  .xdialog -b $dname +ty
  .xdialog -g $dname +b $rgb(20,20,27)
  .xdialog -c $dname 1 line 20 44 50 1 simple | .xdid -C $dname 1 +b $rgb(255,0,0)
  .xdialog -c $dname 2 line 43 20 1 50 simple vertical | .xdid -C $dname 2 +b $rgb(255,0,0)

I found a temporary workaround to fix this problem. If add text through the command "/xdid -t $dname 1 $str($chr(8195),50)", where instead of letters for writing will be used (wide space), which will be cloned for a certain number of characters, this will help to draw a colored line in the desired size. But at the same time, another problem arises, which consists is that, if such drawn lines are long enough and there will be a lot of them, then would need to use a lot more characters to color the line, and in which case, when stretching (resizing) the dialog box, there will be a noticeable large deceleration (braking) for the window to refresh.

So, this method is not suitable for regular use in resizable dialog boxes, and may not be a stable solution to this problem. Therefore, it is obvious that something needs to be changed in the code so that you can draw simple colored lines without using text, as it was originally intended. Perhaps this will give some hints on how can to fix this problem. Thanks in advance.

Here's a modified script to help demonstrate how to draw different colored lines:

alias F5 { line_test }
alias -l line_test {
  if ($dialog(line_test)) .dialog -x line_test | else { .dialog -m line_test line_test }
}
dialog -l line_test {
  title "Line test"
  icon $mircexe,0
  option pixels
  size -1 -1 380 165
}
