From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; m18) Gecko/20010104 BuildID: 2001010404 Reproducible: Always Steps to Reproduce: 1. Open a page with enough text. 2. Press down left mouse button somewhere on the page 3. Without releasing a button move a mouse down Actual Results: Page scrolls down but every line covered by the selection gets some noice at the end. Looks like this only happens on Windows.
I tried to reproduce this (Build 2001010420 on winNT4), but I can't see any noise when scrolling this way. Could you attach a screen shot? Changing component to Layout.
Component: Browser-General → Layout
Additional info: This happens not on every page, but on a page with wide text (like the one provided). If this happens not only glitches appear, they also move. Screenshot soon.
I am also seeing this, squares and random letters appear at the end of lines. I've also observed this in a couple of mail messages. Over to selection.

Okay, on that w3.org page I can see it now, too. Confirming bug.
Status: UNCONFIRMED → NEW
Ever confirmed: true
I see this in lots of pages. Ugly, embarrassing, should investigate for beta1...
Summary: select and drag to scroll adds artefacts to line ends → ASCII characters show at line breaks during selection
This bug is also visible at resource:///res/samples/test2.html, in the text over the gears (at the bottom).
Reproduced it in Windows98 Mozilla 0.7 (2001010901). I've narrowed it down to the following criteria: The more text in the page, the more frequent noise. Also it rarely immediately appears after highlighting, but only after a few pages of it (up or down). Sometime's there (appears) not to be a character, just blue highlight at the end of a line Even in pages with plain text it does this, so it doesn't have anything to do with HTML or tables (I guess) After scrolling up and down (with scroll bar) the bug disappears (possibly the bug is only in select drawing function?) They're not random characters, always the same ones (atleast in one session, might be dependent on whatever's in memory there) After playing with for awhile I'm pretty sure it has something to do with it scrolling too fast and it's grabbing bits and pieces of whatever text was already there. But that's just a hunch...
