1646282 - PDF with long page cut off

Status: RESOLVED DUPLICATE of bug 1713266

(Firefox :: PDF Viewer, defect)

Description

[john99991]

Attachment: 1000.pdf

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0

Steps to reproduce:

Open a PDF with a long page.

Actual results:

At some point, the PDF is not rendered anymore and the screen is white instead. In addition, the rendered resolution is quite low.

The point at which the PDF is cut off can be influenced by zooming in or out.

At first I thought the bug might be caused by a render buffer with some maximum height, but the x-axis and y-axis are drawn all the way to the bottom, so I am not sure what the cause is exactly.

Expected results:

The entire PDF should be rendered. The PDF is rendered correctly in Okular and Chromium.

I can still reproduce the issue on the latest Firefox versions even on W10 and MacOS 10.15.7 so I'm going to update the flags accordingly.
It does occur with both WebRender ON and OFF.
