hello there, i'm using odoo 12 with wiget_pdf->pdfjs.
I am facing this problem (img) when I view pdf files in a frame (chrome and edge), I think it is render-font problem.
TIP: if i use Firefox browser this not happen, it works fine.
Thanks in advance
it is a Chrome/Chromium bug already reported. https://bugs.chromium.org/p/chromium/issues/detail?id=1404710#c11
