Vertica lines are missing when exporting to PDF/PNG[Vue.js]


I’m exporting my gantt to PDF/PNG and vertical lines in timeline are missing.
I try to set smart_scales to false and reinit Gantt, but it does not works.
Do you have any idea why its not working ?

        this.gantt.config.smart_scales = false;
        this.gantt.config.smart_rendering = false;

        const fileName = getGanttExportFileName('pdf');
        const css = getGanttCss();

        // noinspection JSUnresolvedLibraryURL
        const fontAwsome = '<link rel="stylesheet" href="">';

            name: fileName,
            header: `${fontAwsome} <style>${css}</style>`,
            locale: this.$localization.getDhtmlxCulture(),
            raw: true


I tried to reproduce your issue in the following demo, but it seems to work correctly:
Probably, the issue is related to the Gantt configuration, but it is hard to suggest what might be wrong as I don’t see your code. Could you please provide the simplified demo where I can reproduce the issue locally?


You can reproduce it setting gantt.config.static_background = true.
Anyway, I was able to fix it setting is to false before export, thanks for your help
