When adding comments the captcha code displays only lines, no letters.

We are using CPG 1.6.03, the problem happend when upgrading to PHP 7.2.
The same php.ini file is used and of course GD2 is enabled ("extension=php_gd2.dll").
Here is how captcha.php displays: https://www.forumancientcoins.com/Ancient-Maps/captcha.php
And here is DrawCharacters() function from captcha.inc.php
function DrawCharacters() {
// loop through and write out selected number of characters
for ($i = 0; $i < strlen($this->sCode); $i++) {
// select random font
$sCurrentFont = $this->aFonts[array_rand($this->aFonts)];
// select random greyscale colour
$iRandColour = rand(0, 100);
$iTextColour = imagecolorallocate($this->oImage, $iRandColour, $iRandColour, $iRandColour);
if ($this->bCharShadow) {
// shadow colour
$iRandColour = rand(0, 100);
$iShadowColour = imagecolorallocate($this->oImage, $iRandColour, $iRandColour, $iRandColour);
}
// select random font size
$iFontSize = rand(16, 25);
// select random angle
$iAngle = rand(-30, 30);
// get dimensions of character in selected font and text size
$aCharDetails = imageftbbox($iFontSize, $iAngle, $sCurrentFont, $this->sCode[$i]);
// calculate character starting coordinates
$iX = $this->iSpacing / 4 + $i * $this->iSpacing;
$iCharHeight = $aCharDetails[2] - $aCharDetails[5];
$iY = $this->iHeight / 2 + $iCharHeight / 4;
// write text to image
imagefttext($this->oImage, $iFontSize, $iAngle, $iX, $iY, $iTextColour, $sCurrentFont, $this->sCode[$i]);
if ($this->bCharShadow) {
$iOffsetAngle = rand(-30, 30);
$iRandOffsetX = rand(-5, 5);
$iRandOffsetY = rand(-5, 5);
imagefttext($this->oImage, $iFontSize, $iOffsetAngle, $iX + $iRandOffsetX, $iY + $iRandOffsetY, $iShadowColour, $sCurrentFont, $this->sCode[$i]);
}
}
}

Sorry, for the first link you must be logged in, I'm sending here a screen capture:
-
And the upgrade was from PHP 7.1 to PHP 7.2, nothing changed to CPG, it is still version 1.6.03.

Please upgrade to the latest release. If the problem still exists we can help then
