Created attachment 81384 [details] testcase Open the attached html file. Reduce the window width to show a horizontal scroll bar and perhaps 2 columns of text. Reduce the window height to show a vertical scroll bar. With that window size, scroll towards the right and you will notice blank / whitespace. Other columns should have been there. Now scroll up and down and those columns will appear. Another way to see the disappeared columns is to select the text with the mouse. Similar downstream issue http://code.google.com/p/chromium/issues/detail?id=71278 that shows webkit-column-width issues on a page like http://en.wikipedia.org/wiki/Rajinikanth Though unsure if that exposes more issues than what my test case shows, but is quite similar. More issues with webkit-columns can be seen in Bug 45138 (testcase of this one also shows the above disappearing text issue) and Bug 41796.
Created attachment 81385 [details] html testcase This is the actual text case, the other was an image
Created attachment 466879 [details] WebKit ToT Screenshot I am not able to reproduce: 1) Reduced window size to make horizontal scrollbar to appear 2) Reduced window size to get vertical scrollbar 3) Did text selection or scroll-up and down etc. to check if some content / text appear but nothing happened. I think we don't have this bug and WebKit has evolved that this bug is no longer applicable. CCing - Alan and Simon for any input but I think we can close it and if this issue, I think we would be able to get this with other test cases etc.
Yeah, this looks to have progressed.
