1109194 - 34.0 introduced a number of rendering bugs on every page

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: Toolbar, defect)

Description

[jp]

Attachment: screenshot1.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:33.0) Gecko/20100101 Firefox/33.0
Build ID: 20141018042246

Steps to reproduce:

Open any webpage or even about:config, the bugs are visible everywere.


Actual results:

1) The right side of the screen has some weird artifacts that mess up the graphics/text on every page.

2) Fast scrolling sometimes leaves excess horizontal lines on the screen.

See the attached screenshots. Faulty rendering is marked with red circles.


Expected results:

The artifacts/excess lines should not be present, as they weren't in the earlier Firefox versions.

Thanks for the report! This is probably related to bug 1009306.

Right, looks like a dupe. I have not seen the problem as exaggerated as much as the screenshot before so I'm not comfortable duping this.

Erm... Are you saying that you don't believe that the bug is there? Sorry, english is not my native language, so I don't really understand what you mean by calling it a "dupe".

This might be the same issue in bug 1009306 (see screenshots in that bug).

This looks more like bug 1073554 to me. Does this only happen when panning?

The horizontal lines appear occasionally when scrolling the page, not always, though. The "misplaced" pixels on the right side of the screen are present when the page is first loaded (i.e. no zooming/panning). zooming in actually fixes the problem, but when you return to the default zoom they appear again.

Hello,

Is this still an issue?
Can you reproduce it on the latest Firefox release? (v. 50)

Haven't gotten any other reports of this issue and the original reporter seems nonresponsive.
