1721402 - v86.0.1 on Debian Linux ppc64 reverses color bits in PNG and BMP

Status: UNCONFIRMED

(Core :: Graphics: ImageLib, defect)

Description

[Dennis Clarke]

Attachment: ff86_ppc64_color.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:92.0) Gecko/20100101 Firefox/92.0

Steps to reproduce:

Attempt to access both a png image and a bmp image.

Actual results:

Colors seem wrong.

Expected results:

With test data that is in PNG 16bit RGBA format as well as PNG 8bit RGBA formap we see that colors are wrong. Seems as if the big endian ppc64 backend client is not able to render the colors in the correct byte order onto the frontend Debian stable amd64 X11 server. Also tested with 24 bit BMP format ( R8G8B8 ) and also 16 bit BMP R5G6B5 format we see colors wrong. Scaled images are far worse with what seems to be entire color channels missing. FireFox nightly 92.0.a1 on Debian stable amd64 seems to work just fine.

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

The Bugbug bot thinks this bug should belong to the 'Core::ImageLib' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

[Timothy Nikkel (:tnikkel)]

Oops, saw that you tested on amd64 with nightly.

Comment 4

[Dennis Clarke]

I will try to build nightly on the ppc64 machine however that sounds very tricky. I will check the buildconfig and whatever else I can dig into and may get a nightly build. You would be surprised that there are still a bunch of ppc64 users out there.

[Dzmitry Malyshau [:kvark]]

Marking as S4 given that PPC is Tier-3 platform.
An "about:support" would help.

comment : Good to see that anything big endian at least works. I am troubled by code written on little endian systems that seems to just break when it is compiled and run on sparc or ppc64 or some other big endian machine.
