138521 - Mis aligned text when scrolling page

Status: RESOLVED DUPLICATE of bug 80530

(Core :: Layout, defect, P4)

Description

[Jimmy Sieben]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.0rc1)

BuildID:    2002-41711

Scroll the page with the mouse wheel - eventually you will see a line of text
where the top doesnt align with the bottom. I **believe** this happens when the
line of text is half-way on the screen and half-off, but I have not confirmed it.

Reproducible: Sometimes
Steps to Reproduce:
1. Open a page with a lot of text, like Slashdor
2. Scroll around with the mousewheel
3. Look **carefully** for lines of text that get misaligned
4. Verify by selecting and deselecting the text that the line goes back to normal.

Actual Results:  Text tops misaligned with text bottoms

Expected Results:  Text should be perfectly aligned, as all the other text on
the page is. Selecting/deselecting the text "fixes" the alignment.

This is an ugly, embarassing bug.

Attached is a screenshot to demonstrate the bug. The last line of text in the
window shows the misalignment.

Reporter what DPI (resolution) is your system set to and what DPI is set in the
Mozilla preferences? If the DPI is 120 or 125 this is a dup of bug 80530

Is this any way dup or related to bug 87738..?

Marking WORKSFORME because there has been no response to request for extra information for more 
than a month...

Reporter, if you can provide the DPI of Mozilla and of your system please 
reopen this bug.

Im using 120 dpi fonts on Win2k, Mozilla RC3 (2002052306)

Still seeing the problem.

Oops, forgot to note that Mozilla DPI is set at 96dpi, with checkbox set for
Allow documents to use other fonts.

Hope this helps.

Thanks for the info. This is a dup of bug 80530 (if you look at 
http://bugzilla.mozilla.org/show_bug.cgi?id=80530#c63 you will find someone 
reporting that changing the DPI to 96 in mozilla did not fix the problem at a 
simlar DPI and the screenshot shows the classic one pixel shift).
