131444 - Paragraph moves 1pixel up and down on repainting of scrollable page

Status: RESOLVED WORKSFORME

(Core :: Web Painting, defect)

Description

[Malx]

I have seen this many times on different pages using lates Mozilla for linux and
win32.
I can't find if this bug already submited.

Here is example URL.
1. This page contains script which moves green circle images to follow mouse
2. Open page on 1024x768 (page will not fit the window and you'll see scroller).
  In my case I could see all content down to line "And take a look at..."
3. move mouse over links and paragraphs and you'll see that <p>s moves up and
down 1 pixel.

This will not heppen if all page fit window size (no scrollers)

worksforme, linux build 2002-04-12-21.  Are you still seeing this with current
builds?

I still see same error on 2002041707

If I move cursor over paragraph and:
1) JavaScript is on
2) Page is not fit screen and there is scroll bars
3) green thing is following cursor

I see lines moving up and down 1 pixel.

[Malx]

sorry for silence

I still exist in:
Mozilla/5.0 (X11; U; Linux i686; uk-UA; rv:1.2b) Gecko/20021028  04

URL: http://cad.kiev.ua/~malvin/
Resolution(?): 1024x786 (window size is ~968x730)
Action: move mouse over big letters "Alexey Medvedev" from left to
  right (make it 3-5 times slowly to see effect). 
You whould notice that letters are partially displaced by 1 pixel.

[Devoti Paolo]

maybe dup of bug 117419

Comment 8

[Malx]

 No. That bug is about bold font.
But this one is not. This one (see attached images) about corrupted image in
text _and_ graphics.

 And it still exists.

I get "connection refused" at the URL.
malvin: if this is still a problem can you update the URL or attach the page to
this bug ("Create a New Attachment").  if it's not a problem anymore, please
mark WORKSFORME

:(
1) the URL is OK and will be! I's my home page! (also it may be unavaliable for
short time up to a day)

2) the bug is still here. I could add that moving "JS mouse followers" over
image also will show this bug

[Johnny Stenback (:jst)]

Hmm, worksforme too. Odd...

Attachment: testcase

moving the mouse over the <hr> shows redrawing problems with linux trunk
20030713.

anything in the top ~10 pixels of the <div> is drawn 1 pixel too high.	moving
the mouse up so the <hr> moves into the bottom of the <div> part redraws the
<hr> properly.	if the <hr> leaves the <div> through the top, left or right, it
is not redrawn.

this looks like a views problem...

Re comment #6, confirming a display problem with the given URL on
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030624
It's *not* the same one described in this bug (the displacement is horizontal),
though it might be related.

Comment 15

[Bill Gianopoulos [:WG9s]]

I cannot duplicate this bug using this build:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111 Firefox/1.5 ID:2005111116

There have been several WFM comments from other WIN32 users.  There have been subsequent comments that it still fails, but all from Linux users.  Despite the fact that the original report was win and linux, I am changing the OS on this to Linux for now.

Please post a comment if you still see an issue with Windows.

[Andrew Schultz]

Worksforme on linux as well, even with Mozilla 1.4 and 1.0, which would have exhibited the bug before.

resolving WFM.  please reopen if you're still seeing it.
