Reproducible: Always Steps to Reproduce: 1. Happens spontaneously. I have no idea how this started or how to stop. 2. 3. Expected Results: It shouldn't have these strange lines!

Confirmed on Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5b) Gecko/20030827. Somebody please take a look, I can try to help if needed. It was working fine on 1.4, and appeared right after I upgraded to 1.5b. It seems it only happens to IFrame though. System: WinXP SP1, SiS 650-740 Video Card, 512MB RAM.

Happens on WinXP SP1 as well using Moz 1.5 rc1 at the URL http://bugzilla.mozilla.org/enter_bug.cgi Marking Flag blocking1.5 with ? to request a review.
Flags: blocking1.5?
What screen DPI are you using? Does change the DPI affect this at all? Does it happen only on certain pages, or all over the place? If only on certain pages, can you make a minimized testcase?

So the original report says it happens with 1.4 and comment #4 says it doesn't happen with 1.4. Do we know when this regressed? I can't reproduce with the latest 1.5 branch builds on windows.

I don't know about 1.4, but it certainly happens with 1.5 rc1 (Gecko/20030916) on my laptop (happens on both a screen resolution of 1400x1050 and 1280x1024).

Confirming with Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5) Gecko/20030925 The whole browser (and even mail client) are corrupted during operation by vertical and horizontal lines -they appear not only inside "work area", but even in button panel etc. It looks for me like some rendering buffer synchronisation failure or so. If I move page DOWN using the mouse ang right bar, the screen is corrupted, depending on how fast i move -the slower, the more lines. If I move the page UP the same way, the lines disappear in moved parts of screen. If I open terminal window over Mozilla, and then close the terminal, the parts of Mozilla screen that were UNDER the terminal window, are suddenly alright. I use GNOME 1.4 under Debian Woody on app server, and I am connected thru LTSP thin client. No other app has such problems, its Mozilla only. OpenOffice.org, Eclipt Roaster and XCDROAST renders well, as well as whole desktop. One more thing: If I change size of the whole Mozilla window, the screen is "corrected" -all buggy lines disappear. But any other actions render new lines again.

I experimented slightly, and the problems disappear for me if I swap my 4MB STB Velocity (Riva128) by 1MB S3 videocard and thus X server S3 version 3.3.6 is used. My conclusion is that the problem might be somehow connected to X version 4.1 and higher. Or there is other connection between videocard used and problem appearance? Don't know..

Well, I'm using Windows on a laptop (no X server involved or installed).
