Description

9 years ago
User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; de; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; de; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6

When scrolling a page, BITBLT operations don't seem to have been programmed correctly in FireFox.

Portions of the screen are scrolled separately, resulting in a jagged display while scrolling.

(The split appears vertical. If the effect was horizontal, I'd call it a v-sync problem...)

Reproducible: Always

Steps to Reproduce:
1. Open any page (the example page given contains a green horizontal bar which demonstrates the effect quite visual)

2. Resize the window to be at least 1500 pixels in width. (The effect doesn't occur if the browser windows is smaller.)

3. Scroll up and down...
Actual Results:  
While scrolling, the browser content seems to scroll in separate parts. The content appears jagged.

Expected Results:  
Browser content should appear to scroll smoothly.
