598754 - [D3D9] Adobe reader plugin lets previously painted content from other tab show through

Status: RESOLVED WORKSFORME

(Core :: Graphics, defect)

Description

[Benoit Jacob [:bjacob] (mostly away)]

Attachment: glitch

Steps:
 1. Set gfx.direct2d.disabled = true (not necessary, but I thought you'd find
it intersting to know this happens not only with Direct2D)
 2. Restart firefox, go to mibbit.com in the first tab,
 3. open a new tab, go to:
  http://www.khronos.org/registry/gles/specs/2.0/es_full_spec_2.0.24.pdf
 Using the Adobe PDF Reader plugin.
 4. go back to mibbit tab and then back again to PDF tab.

Result: attached screenshot.

I have windows 7, UA string:

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b7pre) Gecko/20100921
Firefox/4.0b7pre

This seems to be independent of whether Direct2D is enabled.

Confirmed.

Note: i had to switch between the tabs several times to reproduce this.

Awesome work Alice0775!

CC'ing Joe...

There are 2 changesets in this regression window. One of them is enabling D3D accel. Can someone check if the bug persists with D3D disabled? Set layers.accelerate-all=false and -none=true. (I'm not on Windows at the moment).

If the issue persists, one should look at the other of these 2 changesets.

[Benoit Jacob [:bjacob] (mostly away)]

*ahem* no sorry, both changesets are D3D specific...

Comment 5

[Alice0775 White]

Anyway, I set prefs as follows and confirmed that the problem does not happen.
layers.accelerate-all;false
layers.accelerate-none;true

ok, well that's interesting, you proved that the problem is with d3d acceleration!

I Force enabled D3D9 by user_pref("layers.accelerate-all", true); in user.js,

BTW;
During loading of the PDF, whole contents area of pdf tab becomes the image of another tab when I switch tabs between PDF tab and onother tab.
And It happens till loading of the PDF is completed.

Is this behavior Bug? did already file a Bug?

I have no idea whether it's a bug, I'll let them answer that.

Experiencing same bug. 
Also happens with firefox 3.6.11though. Since I deal a lot with pdf online, I feel like this bug has always been part of firefox, as far as I remember. Would be nice if adressed though...
