548967 - Images rendered for large part black, when loaded for the first time

Status: RESOLVED FIXED

(Core :: Graphics, defect)

Description

[Martijn Wargers (dead)]

In about:config:
gfx.font_rendering.directwrite.enabled  set to true.
mozilla.widget.render-mode set to 6(RENDER_DIRECT2D).
Then restart.

After that, when loading a large image, a large part (the bottom part) can get black.

Just reload a few times.

Attachment: Test image

Only a portion of this image is actually display so click the image enlarge it (until the taskbar is fully shown at the bottom).  I had to click it four times to enlarge it to it's full size.

A work around seems to be select all or ctrl-a. I've done this on all of the images or pages that weren't fully rendering the images and after hitting ctrl-a, they all show up.

Well, the work around seems to work on images that are cut off, but not displaying a black area. Also, if you drag the cut off image, with or without a black area, you can see the full image as you're dragging it. Weird.

I suspect this is part of the flush/markdirty problem. I didn't test our patch there extensively enough apparently.

Comment 6

[Bas Schouten (:bas.schouten)]

Caused by my incorrect assertion on bug 534787 that the patch there wasn't actually needed.

Resolved with fixing of bug 534787.
