1679384 - PDF Viewer is cutting PDF Table contents (Forms?) on screen and on printout since V83.0

Status: NEW

(Firefox :: PDF Viewer, defect, P3)

Description

[bernd.seene]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36

Steps to reproduce:

Customer uses Linux (Ubuntu), Firefox V83.0.
My customer uses a web based tool that creates PDFs on demand with many prefilled tables/forms on it.
The PDF is then opened and shown in a new Firefox tab.

Actual results:

Since V83.0 the tables/forms in the PDF are shown with a blue-ish background (seems to be UI change, so only noticing it) and some cells (e.g. with a date in it) are cut off, so DD.MM.YYyy is only DD.MM.YY with yy missing.
If you print this page on a real printer the date is printed with bigger font size than on screen so that only DD.MM is printed out (no YYYY at all).
In another cell the special german "Umlaut" letter, e.g. 'ö' is not printed, but left out in the word completely.

With standard Ubuntu PDF Viewer there is no problem: The same PDF is shown on screen and on printout (with real printer) with Ubuntu standard PDF viewer correctly, so it must be a firefox only issue.

Expected results:

There should be no cuting-off in tables/forms on screen and on print.
There should be no letting out of german "Umlaut" letters on print (I do not know if it also misses on screen because it was only presented to me on a printout)

I am not sure If I can attach some PDFs here to see for the public. I will check that. But I can send 1 or 2 PDFs to someone wo wants to have them, so they don't go public for everyone to see.

BR, B.S.

This PDF shows the bug on Linux (Ubuntu 18.04) with Firefox V83.

I took a screenshot on my VirtualBox Ubuntu 18.04 Linux and could recreate the DD-MM-YY <-cutoff Bug. I marked the cutted of region both in the visible Firefox window and in the Ubuntu PDF Viewer (where it is shown without the bug).

I printed the PDF with Firefox to the Ubuntu File printer and chose PDF as output format. In any PDF viewer I tried you see the DD-MM <-cutted bug

With my Virtual Ubuntu 18.04 I could not recreate the german Umlaut bug I saw at my customer, but lets do that one step at a time.
I hope you can review the bug better now.

This is a regression from supporting filling AcroForm forms.

Printing seems to work well now, though the text is still cut off in the viewer.

Still problematic for me on Linux with a hidpi screen. Maybe it depends on the OS or the resolution of the screen?
