page-down results in 2-3 rows of pixels skewed at page overlap boundary. see the URL, fourth line of text. scrolling does not always result in skew but skew is reproducable. as seen in the screenshot, the skew may not span entire window. the rule seems to be "skew left to right through the first anchor text". some lines without anchor text are skewed all the way across. version: CVS updated 2002-04-05 os: redhat 7.0 X: XFree86 4.0.3

Is this bug 80530? Or see bug 134942.

or bug 63336, or the list of possible dupes in bug 63336 comment 10

bug 129400 looks identical -- horizontal pixel shift during scrolling marking this as a dupe. *** This bug has been marked as a duplicate of 129400 ***

Different from bug 80530 in that they report PageDown does NOT cause the problem when it is what does cause the problem for me. Couple addition details: 1) pixel skew doesn't always affect entire lines. sometimes does. but always left to right. 2) any kind of expose/refresh causes the skewed text to be redisplayed without the distortion. just makes getting screenshots tricky.

the real problem for almost all of the off-by-1 pixel bugs is roundoff of pixel positions, which is discussed in 63336. the effect will show up in different ways depending on dpi, font size and any number of other things. see bug 122577 comment 19 for a possible workaround
