Reproducible: Sometimes Steps to Reproduce: 1. Open attached html file. 2. Click on slider and drag left and right. Actual Results: Redraw isn't always performed correctly, see attached screenshot. The artifacts vanish on the next redraw, e.g., by clicking on another window, or clicking on the slider again. Expected Results: Redraw should always be correct.

Confirmed on Windows XP. Regressed between 2007121800 and 2007121900. Regression window is: http://bonsai.mozilla.org/cvsquery.cgi?module=PhoenixTinderbox&date=explicit&mindate=2007-12-17+22%3A00&maxdate=2007-12-19+02%3A00 Caused by Bug 24998 or Bug 406458? I see also that it continues dragging after mouse up but I think this is a different bug

Well it is bug 24998.
Blocks: 24998
Status: UNCONFIRMED → NEW
Ever confirmed: true
Flags: blocking1.9.2?
Easiest way to reproduce is clicking in the gray part.
Mmh, that's strange. It doesn't react on mouse clicks at all on OS X. I only see a gray bar.
It is not the border radius drawing itself that is the problem, but the 'dirty rect' calculation. The change of the width of the inner div (#light) doesn't force redraw of the correct piece.

The standalone testcase is much nicer. :-)
Double clicking in the gray area in the standalone test-case https://bugzilla.mozilla.org/attachment.cgi?id=351766 seems to remove the artifacts and forces a correct re-draw unless I'm completely not understanding this bug. ~B
(In reply to comment #12) > WFM on Mac trunk. Fixed? Latest Linux Minefield works fine here.
