600804 - Plugin test page causes theme abnormal look

Status: RESOLVED DUPLICATE of bug 545892

(Core :: Graphics, defect)

Description

[Maniac Vlad Florin (:vladmaniac)]

Attachment: screenshot

Build identifier: Mozilla/5.0 (Windows NT 6.1; rv:2.0b7pre) Gecko/20100929 Firefox/4.0b7pre

===========================================================================

Prerequisites: 

Create a fresh, clean FF4 profile. 
Use default theme. 
URL to test with: http://hg.mozilla.org/qa/litmus-data/raw-file/tip/firefox/plugins/plugin-test.html

===========================================================================

Make sure default theme is on. 

Steps: 
1. Visit http://hg.mozilla.org/qa/litmus-data/raw-file/tip/firefox/plugins/plugin-test.html
2. Wait for the test page to load
3. Inspect theme, menu and toolbar UI

===========================================================================

Result: Loading of plugin test page causes themes to crash, causing some sort 
of transparent canvas in background. Furthermore, text does not render correctly and sometimes becomes blurry and shadowed. 

Note: This was seen in other betas also, but was not always reproducible 
until now. 

Cause of this abnormal look might not be this test-page itself, as this 
can occur in other situation also. The plugin page is the only url I could 
come up with to have a reproducing algorithm. 

See screenshot also.

Maniac Vlad, what do you mean by "causes themes to crash?"

Comment 3

[Maniac Vlad Florin (:vladmaniac)]

theme layout (canvas, colors, graph items), menus (default or custom), icons form a theme. When these are broken I understand that we have a theme crash. Apologize if being ambiguous.

OK. I think this is encapsulated in bug 545892.
