802758 - Firefox on Secondary Screens on Full Screen Border Rendering Problem

Status: RESOLVED INCOMPLETE

(Firefox :: Untriaged, defect, P3)

Description

Attachment: ff_whiteline_bot.jpg

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:15.0) Gecko/20120830 Firefox/15.0
Build ID: 20120830123745

Steps to reproduce:

Put firefox on full screen mode in a non-primary Windows Monitor


Actual results:

I turned the browser into full screen mode in a monitor that didn't have a windows task bar (i.e. it wasn't my main screen) and a white, very annoying (especially on dark themed websites) white line is always present at the bottom, this is present and EXTREMELY visible in the provided screenshot.

PS. I've put as a valid version the 15 branch, but this is present since forever (for past releases)...as well as and in the nightly releases of Firefox (that as of late are really, really buggy!)

Please, pretty please fix this... or point me to the code that fixes it so I can fiddle with it.

Tx.


Expected results:

Proper rendering of the bottom

Andreas, could you try with hardware acceleration disabled in Firefox 
(Options > Advanced > General, then restart FF to apply).

Does it fix the rendering issue?

NB: update to FF16 before, because FF15 is EOL, please.

Hi,

 I've tried all versions of Firefox... the issue is present in all of the releases as well as nightly builds (I think I said that already).

 The issue is not resolved by disabling hardware acceleration, any more ideas?

Do you remember an old version where the issue wasn't present? (whatever if it's an old version like FF4 or FF10)

Comment 4

[andreas.grammenos]

No,

 But I can remember that all versions of Firefox that I've used had this problem, if that helps.

What's the resolution on your secondary monitor? 100%?

Is it possible for you to test with a new Windows 7 session with default prefs (for monitors)?

Hi,

 Thanks for the swift reply. This happens with with varying resolutions, the secondaries monitors that I've tried it are the following:

 1680x1050
 1920x1080
 1920x1200
 2560x1440
 2560x1600

 Weird thing is that in one of my computers the issue is not present.

Hello Andreas,

I just found your bug-report again and want to ask you if this was ever solved?
I use this config every day and never saw this on actual firefox versions.

thank you for a short feedback
