When a page is loaded the drawing surface is cleared repeatedly, to black, then grey, then black, then grey. Built from M13 without any modifications, Redhat Linux 6.1, Processor K6 2 475Mhz, 64Mb ram.

Assigning all open "nobody@mozilla.org" bugs to "leger@netscape.com" to weed thru.

does the page load at the end? or does it change colors and nothing is displayed? Mozilla does such redraws a lot, as it parses the HTML code. Does this also happen on each page?

slucy@objectivesw.co.uk : can you provide an example URL for this problem? Or, does this happen on 'any' page you load (if so, can you provide some further details on your x-server, monitor, graphics hardware, etc.) -- There are certain pages that will do this 'blank out' while loading, but if this happens on many sites for you, then that would point more towards a particular combination of OS/x-server/hardware etc. Thanks!

It happens on any of the test pages, I've only been running it on local pages. The GTK build does it reliably on this setup on every load of a page. The Xlib build is less noticeable. Because this machine has an SiS 6326 video card imageblt and patblt are switched off and sw_cursor is switched on. In general the whole X system is slow. I'd put it down to a slow graphics engine making obvious something which would normally be hidden. In any event it looks as if there are too many invalidate rectangle processes going on.

reassigning browser-general bugs (again!) so triagers can find all the bugs with one query.

reporter - could you please try m14? thanks

I can't reproduce it with M14. I'd guess the changes removing all the reflowing fixed it.

calling this worksforme as per reporters comments.

marking verified tested on linux build 2000032208. i know there is a bug logged that says background is getting painted twice. And there used to be a bug (which has since been fixed) that affected at least bugzilla where the page would flicker between black and garbage...
