Reported 2006-03-01 14:24:28 PST
Nightshift build 2006-02-28; recreated on new user account. Unable to recreate in Safari 2.0.3. Scrolling causes incomplete drawing of <ul> bullets. 1. Visit URL above: http://en.wikipedia.org/w/index.php?title=Quicksilver_%28software%29&oldid=40652040 2. Using the mouse wheel, scroll down to the long bullet lists in "Interfaces with other applications." Some of the bullets will be missing or partially drawn.

Got the same thing here, they also become vertically "thinner" sometimes. It comes up when using directional keys, doesn't come up when using page up/down. Using build r13060, 10.4.5

Looks like "the regression version" of bug 4855.

#6: Well, I can't recreate this one (7542) on the shipping Safari. Doesn't that make this a regression, or have I erred?

(In reply to comment #7) > #6: Well, I can't recreate this one (7542) on the shipping Safari. Doesn't that > make this a regression, or have I erred? > Sorry, my previous comment was poorly-phrased and incorrect. This bug is a regression, and based on testing with nightly builds, it is probably a regression from the fix for bug 6844.

Thanks for the explanation. Sorry if I seemed offended or something, I wasn't. I was just trying not to ramble. :)

Here it is: + IntRect box(_tx + m_x, _ty + m_y, m_height, m_width); Oops!

Created attachment 6810 [details] patch I also looked through the rest of my checkin to make sure I didn't make the same mistake more than once. I'm not sure how I would create an automated test for this.

Comment on attachment 6810 [details] patch Seems OK to me to check in without a layout test, but maybe someone else will have an idea about how to create one.
