Status: UNCONFIRMED

(Core :: Widget: Gtk, defect, P5)

Description

[Guido Trentalancia]

Attachment: firefox53-rendering-issue.png

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/605.1 (KHTML, like Gecko) Version/11.0 Safari/605.1 Epiphany/3.26.2

Steps to reproduce:

- Build firefox 53.0.3 or 52.0.2;
- Start firefox.


Actual results:

The firefox window is not rendered properly. See attached screenshot.

There are missing icons (on the top right part of the window), however after moving the mouse over the missing icons, the icons are rendered properly.

It is impossible to use firefox.


Expected results:

The firefox window should be rendered properly.

Similarly to icons, sometimes parts of the currently loaded web page are rendered only after passing over them with the mouse pointer...

Comment 2

[Guido Trentalancia]

The problem must be related to rebuilding after some recent library update (Gtk?).

Please make sure you have the latest graphics driver: https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration

Comment 4

[Guido Trentalancia]

I have the latest graphic drivers installed. That's probably the point, because it was working properly with previous library releases...

Also, I have tried disabling webgl and the graphic hardware acceleration as suggested in the above mentioned web page, but nothing changes: it does not render properly !

1) What linux environment is this on?
2) could you please try a newer release to see if it's addressed? 56 is our current release version for users.

Comment 6

[Guido Trentalancia]

I am sorry but I cannot test more recent firefox releases because they depend on rust which I do not want to install (as it requires external binary code and cannot be built entirely from source code).

Comment 7

[Timothy Nikkel (:tnikkel)]

Pretty sure you can build rust from source, no?

Comment 8

[Guido Trentalancia]

No the rust compiler is dodgy, during bootstrap it tries to download binary stuff from the network:

./x.py build
curl: (6) Couldn't resolve host 'static.rust-lang.org'

spurious failure, trying again

Comment 9

[Timothy Nikkel (:tnikkel)]

Why do you think its downloading binary code?

Comment 10

[Guido Trentalancia]

I think it's downloading a pre-built compiler for the first stage. I do not agree that the rust compiler downloads stuff from the network.

That's why I decided not to use firefox releases after 53.0.3.

Can we please get back on theme (this bug) ?

Comment 11

[Timothy Nikkel (:tnikkel)]

Well if you aren't going to use a newer firefox there is no point fixing this bug.

./mach bootstrap will download a prebuilt compiler, but you can also build your own compiler. Its all open source so you can see what its downloading.

Comment 13

[Guido Trentalancia]

There is no relation between fixing this bug and the need to use a newer firefox: I think this bug should be fixed so that this release and the previous ones can work fine.

Many other people are also avoiding to use newer firefox for the same reason, so it's good if this bug is fixed because it extends the life of this version.

Comment 14

[Timothy Nikkel (:tnikkel)]

Very very unlikely we will fix anything older than 56 at this point.

Comment 15

[Guido Trentalancia]

Maybe it's time to move to another browser...
