37049 - Scrollbars redrawn incorrectly on incremental repaint

Status: VERIFIED DUPLICATE of bug 34218

(Core :: XUL, defect, P3)

Description

[Gwyn Judd]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux 2.2.14 ppc; en-US; m15)
BuildID:    2000041919

When the page incrementally repainst so as to cause the page to get larger, the
scrollbar is not redrawn correctly. What happens is that the bottom part of the
scrollbar that was there before the repaint remains there, even though the size
of the scrollbar has decreased.

Reproducible: Always
Steps to Reproduce:
1.load the above page. Notice how the text is loaded first and then a few
seconds later the images which causes the page to resize.

Actual Results:  The scrollbar was not rendered correctly. I will try to attach
an image of the effect below	

Expected Results:  The old scollbar image should perhaps be drawn over with the
scrollbar background colour before it is redrawn?	

This only happens if the page is not being retrieved from cache, otherwise it
draws to quickly for there to be an incremental redraw.

This is a excellent bug report. Unfortunately, it's a dup of 
bug 34218 "Scrollbar leaves traces of itself as it shrinks"...
Maybe someone could extend that bug's summary to include more keywords?

who knows. I search and I search and still I find about 50% of my bugs are dups.
Dunno maybe it's something with bugzilla, the query page isn't that good

Thanks for the report. I added "(incremental,paint)" to the summary to help
people find that bug report a little more easily. marking verified
