New issue 6819 by fin...@chromium.org: Optimize the drawing of the tickmarks on the scrollbar http://code.google.com/p/chromium/issues/detail?id=6819 We should look into optimizing the drawing of the tickmarks on the scrollbar. Instead of drawing the scrollbar and tickmarks from scratch every time, we could - for example - draw the tickmarks into a mem DC and blit it to the scrollbar as needed. This also helps limit the work when additional tickmarks are found, since we don't have to scratch the mem-dc each time, we can just add the new tickmarks to it. We currently have code to throttle the invalidation of the content area and scrollbar, which can probably be removed as a result. You'll probably notice this when you have tens of thousands of matches on the page _and_ you scroll or even just hover over the scrollbar (you'll notice Chrome is sometimes pegging the CPU while you hover over the scrollbar). -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
