Status: RESOLVED DUPLICATE of bug 782311

(Core :: Graphics, defect)

Description

[Mike Nicholls]

Attachment: Testcase

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/17.0 Firefox/17.0
Build ID: 20121023124120

Steps to reproduce:

Opened the attached testcase in Firefox 17 beta 3. Scrolled to the bottom of the page, then scrolled up and down the page repeatedly by dragging the scrollbar.


Actual results:

When reaching the very top of the page, intermittently the display of the page content will become garbled.


Expected results:

The page should display normally after scrolling.  I have been unable to reproduce the problem with Direct2D disabled, or in Firefox 16.0.2 or 19 Nightly.

most likely Bug 782311

If you see artifacts use shortcut CTRL+A for "Select All". If artifacts will be gone, this bug is most likely a duplicate of bug 782311

I can reproduce this reliably on OS X, so I doubt it's an exact duplicate of a D3D bug.

http://howtosharpenpencils.tumblr.com/post/35285338188/the-peoples-bailout is another testcase.

I see this on Reddit too. See attachment 680415 [details] for a screenshot of what I get on http://www.reddit.com/r/shutupandtakemymoney/ It basically makes Firefox unusable on such sites.

Was this DLBI fallout? Seems like it's started more recently, at least for this Reddit issue.

I can no longer reproduce this bug on recent nightlies -- is it fixed?

Comment 7

[Matt Woodrow (:mattwoodrow)]

I can't reproduce it either, would it be possible to get a regression range for when it was fixed?

Comment 8

[Virtual_ManPL [:Virtual] 🇵🇱 - (please needinfo? me - so I will see your comment/reply/question/etc.)]

Maybe with fixed bug #782311 ?

Comment 9

[Tim Martin]

I previously saw this, and like the original reporter have an nVidia card.  (2010 MBA.)  How would I go about testing the builds before/after that fix was committed?

Looking on regression range in my bug #782311 :

Good:
https://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2012/07/2012-07-25-03-05-56-mozilla-central/

Bad:
https://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2012/07/2012-07-26-05-28-03-mozilla-central/

The test case was still broken in the 11-10 build:
 https://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2012/11/2012-11-10-03-07-14-mozilla-central/


But works for me in the 11-11 build:
https://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2012/11/2012-11-11-03-07-49-mozilla-central/

I think that's consistent with Bug 782311 fixing this issue?

[Virtual_ManPL [:Virtual] 🇵🇱 - (please needinfo? me - so I will see your comment/reply/question/etc.)]

Looking on commit date, yep. But lets wait on info from Reuben Morais [:reuben] as he also see it's even on OS X

Comment 13

[Reuben Morais [:reuben]]

(In reply to Virtual_ManPL [:Virtual] from comment #12)
Nope, I haven't seen this bug in a while.

Comment 14

[Virtual_ManPL [:Virtual] 🇵🇱 - (please needinfo? me - so I will see your comment/reply/question/etc.)]

So we can close this bug as dupe of my bug #782311 or mark it as WORKSFORME.

Comment 16

[Virtual_ManPL [:Virtual] 🇵🇱 - (please needinfo? me - so I will see your comment/reply/question/etc.)]

Guys which could confirm this issue, I need some more info about your PC specification.

Especially:
-motherboard and chipset info
-GPU working on which PCIe (3.0/2.1/2.0/1.1/1.0)
-monitor info (type, resolution, refresh rate, connected with HDMI/DVI/DisplayPort/VGA

CPU/memory/sound card/PSU/etc is optional



Thank you!

Attachment: CPU-Z report

Here's a report from CPU-Z, hopefully it has all the required information - please let me know if not.  There are two Samsung SyncMaster 740T displays attached using DVI, one of them is using a HDMI-to-DVI cable.
