1904707 - Internal pdf viewer unusable

Status: UNCONFIRMED

(Core :: Graphics: Canvas2D, defect)

Description

Attachment: pdf100%.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:127.0) Gecko/20100101 Firefox/127.0

Steps to reproduce:

Open a odf online

Actual results:

Ayn pdf is transparent, sometimes there is text but if there is it's multiple times superimposed and unreadable. Background is always completely transparent all the way to the desktop.
If I zoom out all the way to 10% it seems to be ok but obviously unsable that way.

Expected results:

pdfs rendered correctly

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Firefox::PDF Viewer' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

It could be helpful to provide the pdf you're showing on the screenshot.
That said could you reproduce your issue in setting the pref gfx.canvas.accelerated to false in about:config (and in reloading your pdf) ?

It was a random pdf that first showed up when I googled. Turns out to be the "Risk" rulebook :)

But the gfx.canvas setting did it for me! All working properly again! Cheers for that :)

This is severe, but has a workaround. The spread of this issue is unclear. Tentatively triaging at S3, but I can see a world where we realistically prioritize this as S2.
