Can you do this test :
1) Change description.

3) Save.

Is description correctly saved ?

yes 😉

I have sames ascertainment with postgresql and apache 2.0 ans last php version.

Fixed !
For information, issue does not occur if you save using [CTRL]+S.

Fix is to replace saveObject() function in /view/js/projeqtor.js from

function saveObject() {
  if (waitingForReply)  {
    showInfo(i18n("alertOngoingQuery"));
    return true;
  }
  if (editorInFullScreen()) return;
  dojo.byId("saveButton").blur();
  submitForm("../tool/saveObject.php","resultDiv", "objectForm", true);
}

to

function saveObject() {
  if (waitingForReply)  {
    showInfo(i18n("alertOngoingQuery"));
    return true;
  }
  if (editorInFullScreen()) return;
  for(name in CKEDITOR.instances) { // Necessary to update CKEditor field whith focus, otherwise changes are not detected
    CKEDITOR.instances[name].updateElement();
  }
  dojo.byId("saveButton").blur();
  submitForm("../tool/saveObject.php","resultDiv", "objectForm", true);
}

For me it work fine ! Big thanks !
