Dhtmlx raw export glitch

When i export the gantt in PDF using raw format the right border of the grid is missing. sometimes it appears when i zoom the pdf.

However this doesnt happens when raw is false.

Here is the screenshot of the exported PDF using raw: true. As you can see the right border of the grid is missing.

Hello Nikolai,
Looks like, it happens because the PDF viewer rounds the line width to 0. It is reproduced in some PDF viewers while other PDF viewers always display the correct line width.
If you zoom in or zoom out, you might see the line in the same exported file. The dev team will check if it is possible to change that behaviour.
Now, as a workaround, you can export with the following style config:

header: "<style>.gantt_grid_data, .gantt_grid_scale {border-right: 1px solid #ECECEC;}</style>"

Here is an example:
