217794 - plugins are rendered at an offset of one pixel, causing an ugly false-border effect

Status: RESOLVED DUPLICATE of bug 193430

(Core Graveyard :: Plug-ins, defect)

Description

[Alp Toker]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5b) Gecko/20030828 Firebird/0.6.1+
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5b) Gecko/20030828 Firebird/0.6.1+

The plugin window is rendered at an offset of one pixel from the origin, causing
one-pixel-thick black lines to be drawn at the outermost north and west
extremities of the plugin. Consequently, one row and one column of the plugin's
window are also lost at the east and south extremities.

This is a blocker for graphics plugins, where display must be pixel-perfect, and
is delaying the release of at least one vendor's Mozilla plugin.

The screenshot shows the problematic Mozilla rendition aside the Konqueror
browser, which renders the plugin properly.

Reproducible: Always

Steps to Reproduce:




Tested with Seamonkey trunk and Firebird

Alp Toker, any chance of an HTML testcase showing the problem?  For example, is
the problem reproducible with Flash?  Is there anything in the document other
than just the <object> tag?  Is the problem only present on Linux or also on
other OSes? (I'm not sure whether you have a way to test other OSes; if you do
not, that's ok.)

[Marek Stępień [:marcoos, inactive]]

This is an obvious duplicate of bug 193430 ("Flash objects have 1px black
borders around them"), which has a screenshot of Firebird/gtk2 and Netscape
7.1/gtk1.

This bug appears in GTK2/XFT builds only (not in the GTK1 ones). 

Resolving as duplicate.
