1015176 - Rendering artifacts with repeated and squeezable page contents

Status: RESOLVED DUPLICATE of bug 1017571

(Core :: Graphics, defect)

Description

[Markus Stange [:mstange]]

Attachment: screenshot

This is happening in today's Nightly, built from https://hg.mozilla.org/mozilla-central/rev/e9b2b72f4e6c , on Mac OS 10.9.3 with OpenGL OMTC.

Steps to reproduce:
 1. Go to http://www.gruene-mainz-bingen.de/home/
 2. Scroll down about half a screen.
 3. Slowly scroll up again.

I suspect bug 1012407.

I can reproduce this. Feel free to back out parts to fix it. I won't be near wifi for a bit but I will provide a fix later (no need wait for that though).

Comment 2

[Andreas Gal :gal]

Fix reviewed over in bug 1012407. Will land it there.

Comment 3

[Andreas Gal :gal]

Trunk is fixed but re-opening this one to investigate why we generate texture coords that are outside (0,0)(1,1) and need to be normalized.

I'm still seeing this on Twitter on a 5/26 Nightly on OSX.

I still see reproducible rendering failures when scrolling a TBPL log [1] horizontally on a 2014-05-29 Nightly:

Could this also cause artifacts when opening a new tab? I sometimes see the tab label and icon distorted. Should I file new bugs for the two issues?

I also see this in 32.0a1 (2014-05-29) nightly build

I also saw this with horizontal scrolling (using touchpad) on the about:telemetry page on 2014-05-30 Nightly

Tim, Irving, Mano: that seems to be Bug 1018127 (which I also see).

Tim: the new tab corruption is something I also see, is probably related, but worth filing. I never managed to get a screenshot.

I get the same on the Gmail inbox view.
I depends on the window with and I only see it if I have the history sidebar displayed.

I did a bisect on it and it identified this:

summary:     Bug 1012407 - Part 7: Use a single GL draw call to draw up to 4 texture quads (r=Bas)

Comment 22

[Bill Gianopoulos [:WG9s]]

My issue was fixed by the recent check-in for bug 1017571.  Since I was having this issuer with AMD/ATI graphics under Linux using the Xorg ATI driver, the issue is evidently not restricted to either Intel graphics or OSX.
