When scrolling with either the scroll bar or the mouse wheel a single pixel line can be droped out. Seems to be always from the bottom as the text / image scrolls up. Much worse when using the mouse wheel. If you place the pointer in the middle of the page and click once then go and click in the URL entry window the page repaints and the missing pixel lines appear. This is with a current nightly build, but I have been having this problem for a LONG time with both release and nightly builds. AMD x86 RedHat 7.2

I also have seen this to happen with Mozilla 1.1 (Debian packaged), and Mozilla 1.2a (compiled myself), but it has also appeared in previous releases; actually in each that I have tried (i.e. greater than M-18), if I remember correctly. The problem is that when scrolling down or up, some full width single pixel horizontal lines are missing. This can also be seen on many pages, and sometimes it does not require scrolling very much. This affects all the content on a web page. Additionally, moving another window across the misdrawn portion causes it to be correctly drawn. Reproducibility: Always (mostly) Steps to reproduce: 1. Go to e.g. http://users.utu.fi/lahtonen/rubik.html 2. Move to the top of the page. 3. Scroll down holding the down arrow key pressed. 4. When you reach the title "Ratkaisualgoritmi", or before, release the down arrow. Actual results: Some horizontal single-pixel lines seem to have been randomly dropped out, and the text looks messy. (I'll attach a screen shot.) Expected results: Page should not have missing horizontal single pixel lines when drawn. Additional information: AMD k6, 400 Hz Linux 2.4.19, and also earlier kernel versions. XFree86 4.2.1, 4.2.0, 4.1.0, 4.0, with SiS 530, or 4.2.0 and 4.2.1 with tdfx.

At the top of the screen shot there are text lines, that miss some horizontal single-pixel lines. When moving another window across these lines, the affected portion of the page is drawn correctly.
