909009 - Message content shows background bleeding through

Status: RESOLVED FIXED

(Thunderbird :: General, defect)

Description

[Joe Sabash [:JoeS1]]

Thunderbird disables HWA by default.
Since bug 907926 landed our message rendering is seriously affected
Enabling HWA via the pref gfx.direct2d.disabled bypasses the problem, but may cause other problems.
See the URL for a screenshot.

Is this due to the same problem

don't know what has happened to url above. Apologies.

problem is that black areas appear on screen instead of bleed-through reported by Joe. These are temporary, random and vary in size from thin bar across bottom of screen to large block covering third of screen at bottom.

Sounds more typical than what I'm seeing.
See some of the dependent bugs in bug 907926

Noted that messages opened in new tab or new window does not show the black areas.
